Ingredients

Water, Pork By-Products, Ocean Fish, Pork Liver, Powdered Cellulose, Chicken Fat, Wheat Flour, Corn Starch, Whole Grain Corn, Chicken Liver Flavor, Calcium Sulfate, Natural Flavor, Locust Bean Gum, Soybean Oil, Choline Chloride, Guar Gum, Brewers Dried Yeast, L-Lysine, DL-Methionine, Carrageenan, Calcium Carbonate, Iodized Salt, Dicalcium Phosphate, Potassium Chloride, Taurine, vitamins (Vitamin E Supplement, Thiamine Mononitrate, Ascorbic Acid (source of Vitamin C), Niacin Supplement, Pyridoxine Hydrochloride, Calcium Pantothenate, Vitamin B12 Supplement, Riboflavin Supplement, Biotin, Folic Acid), L-Carnitine, minerals (Zinc Oxide, Ferrous Sulfate, Manganese Sulfate, Copper Sulfate, Calcium Iodate), Potassium Citrate, Iron Oxide color, Beta-Carotene.

First 5 ingredients

Water - Used to add moisture to the formula. In canned foods, moisture percentage can be up to 80%.

Pork By Products – By-products of pigs.

Ocean Fish – A vague term for fish. Fish is an animal protein source. There are concerns about the quality of fish used to make pet food. Usually it is waste of the fishing industry.

Pork Liver -A nutritious organ meat coming from pork, which refers to pigs.

Powdered Cellulose – Cellulose in powder form.

Ingredients to Point Out

By-Products – The clean parts of named animal other than the actual meat. This can include the brain, bone, blood, kidneys, clean intestines, clean stomach, and lungs. Basically anything from the slaughtered animal except the hair, horns, teeth, and hoofs.

Fish/Seafood - Fish have elevated levels of mercury. Feeding a cat fish every now and then is okay. Long term exposure to fish will cause health problems. Also, the majority of the time fish used for pet food is rank and of poor quality. Unless otherwise stated by the company as 'food fit for human consumption'. This applies to seafood as well.

Cellulose – This ingredient is a fiber source, often used as a carbohydrate substitute. It also has thickening properties. It is a filler and lower quality ingredient. Cellulose can actually come from wood. This is just an example, it doesn't mean wood chips are actually in this food.

Grains – Grains are of poor nutritonal value for cats. Cats cannot digest grains easily. They are in cat foods as a filler ingredient and filler only. Wheat, corn, corn flour, flour, white rice, ground rice, barley, brewer's rice, etc. fall into this category. Ingredients such as wheat gluten and corn gluten also fall into this category as these ingredients originate from grains.

Corn based ingredients – Corn, especially, is hard to digest and a source of allergies, and health problems. Corn starch, while not corn, is corn based and is an unneeded source of carbohydrates. Protein (corn gluten) from corn is not appropriate as cats are carnivores. Corn based ingredients should be avoided if possible.

Calcium Sulfate – A common industrial chemical. It is a cheaper form of calcium.

Locust Bean Gum - A self gelling thickening agent. Combines with other thickening agents to produce desired effects.

Guar Gum - A less harmful thickening agent used in cat food. Still, interferes with protein absorption and is known to cause GI upset.

Carrageenan - Most commonly used as a gelling and thickening agent in cat foods. Non-food grade carrageenan is cancerous. Food grade carrageenan causes GI issues. This is because the food grade carrageenan contains small amounts of pro-inflammatory particles. A highly controversial ingredient as much fear that even the food grade carrageenan will eventually lead to cancer (this has not been proven though).

Zinc Oxide – Artificially produced source of zinc more often seen in non-food materials. This includes rubber, paints, creams, and batteries. Poisoning due to ingesting too much zinc oxide will occur; present in cat food in safe amounts. Many people don't like to see this ingredient in cat food.

Copper Sulfate – Is an irritant and is linked to copper toxicity. Many do not like the presence of this ingredient in cat food because it has many other uses. It can be found in the leather, wood, battery, ink, paint, and metal industries.

Added Coloring – Sometimes known as artificial coloring. Certain colors, such as ‘Red #3’ are cancerous and are banned from uses in human products. Iron Oxide and Titanium Dioxide also fall into the added color category.

Ingredients to Point Out

Vegetables - Vegetables are normally used as a binder and carbohydrate substitute. A grain free cat food could still have a high amount of carbohydrates. Potatoes, sweet potatoes, peas, etc., while not grains, still contain carbohydrates.

Gluten – Gluten is the protein that is found in many different types of grains, including wheat, rye, and barley. Gluten is a protein source. Cats simply cannot digest gluten and use it effectively in their bodies. They need protein from a meat source.

Starch – This includes pea, potato, tapioca starch (flour). Starch is a type of carbohydrate. Cats need carbohydrates, but only very little. The addition of these extra carbohydrate sources make the % much higher than what a cat needs. Cats are not equipped to digest high amounts of carbs. These types of ingredients are mainly in cat food because they are great binders, they bind the food together effectively.

Cellulose – This ingredient is a fiber source, often used as a carbohydrate substitute. It also has thickening properties. It is a filler and lower quality ingredient. Cellulose can actually come from wood. This is just an example, it doesn't mean wood chips are actually in this food.

Guar Gum - A less harmful thickening agent used in cat food. Still, interferes with protein absorption and is known to cause GI upset.

Sodium Tripolyphosphate – This is an inorganic (meaning man made) ingredient mainly used as a preservative. This ingredient is used in other products, such as laundry detergent. It’s an artificial preservative that does not belong in cat food.

Zinc Oxide – Artificially produced source of zinc more often seen in non-food materials. This includes rubber, paints, creams, and batteries. Poisoning due to ingesting too much zinc oxide will occur; present in cat food in safe amounts. Many people don't like to see this ingredient in cat food.

Salmon – A species of fish. Salmon is very popular in the fishing industry. It provides protein and may have elevated levels of mercury. Concerns about the quality of fish used in pet foods.

Pork Liver – A nutritious organ meat coming from pork, which refers to pigs.

Wheat Flour -Powder made from grinding wheat. Cats do not get much nutritional value from wheat flour.

Ingredients to Point Out

By-Products – The clean parts of named animal other than the actual meat. This can include the brain, bone, blood, kidneys, clean intestines, clean stomach, and lungs. Basically anything from the slaughtered animal except the hair, horns, teeth, and hoofs.

Fish/Seafood - Fish have elevated levels of mercury. Feeding a cat fish every now and then is okay. Long term exposure to fish will cause health problems. Also, the majority of the time fish used for pet food is rank and of poor quality. Unless otherwise stated by the company as 'food fit for human consumption'. This applies to seafood as well.

Grains – Grains are of poor nutritonal value for cats. Cats cannot digest grains easily. They are in cat foods as a filler ingredient and filler only. Wheat, corn, corn flour, flour, white rice, ground rice, barley, brewer's rice, etc. fall into this category. Ingredients such as wheat gluten and corn gluten also fall into this category as these ingredients originate from grains.

Corn based ingredients – Corn, especially, is hard to digest and a source of allergies, and health problems. Corn starch, while not corn, is corn based and is an unneeded source of carbohydrates. Protein (corn gluten) from corn is not appropriate as cats are carnivores. Corn based ingredients should be avoided if possible.

Cellulose – This ingredient is a fiber source, often used as a carbohydrate substitute. It also has thickening properties. It is a filler and lower quality ingredient. Cellulose can actually come from wood. This is just an example, it doesn't mean wood chips are actually in this food.

Locust Bean Gum - A self gelling thickening agent. Combines with other thickening agents to produce desired effects.

Guar Gum - A less harmful thickening agent used in cat food. Still, interferes with protein absorption and is known to cause GI upset.

Carrageenan - Most commonly used as a gelling and thickening agent in cat foods. Non-food grade carrageenan is cancerous. Food grade carrageenan causes GI issues. This is because the food grade carrageenan contains small amounts of pro-inflammatory particles. A highly controversial ingredient as much fear that even the food grade carrageenan will eventually lead to cancer (this has not been proven though).

Zinc Oxide – Artificially produced source of zinc more often seen in non-food materials. This includes rubber, paints, creams, and batteries. Poisoning due to ingesting too much zinc oxide will occur; present in cat food in safe amounts. Many people don't like to see this ingredient in cat food.

Copper Sulfate – Is an irritant and is linked to copper toxicity. Many do not like the presence of this ingredient in cat food because it has many other uses. It can be found in the leather, wood, battery, ink, paint, and metal industries.

Added Coloring – Sometimes known as artificial coloring. Certain colors, such as ‘Red #3’ are cancerous and are banned from uses in human products. Iron Oxide and Titanium Dioxide also fall into the added color category.

Green Peas – Nutritionally are very similar to yellow peas, green peas taste sweeter.

Ingredients to Point Out

Vegetables - Vegetables are normally used as a binder and carbohydrate substitute. A grain free cat food could still have a high amount of carbohydrates. Potatoes, sweet potatoes, peas, etc., while not grains, still contain carbohydrates.

Egg/Egg product – The biggest concern regarding egg ingredients is the quality of eggs used in pet food formulas. Usually it is egg waste. Unless otherwise stated by the company as 'food fit for human consumption.'

Starch – This includes pea, potato, tapioca starch (flour). Starch is a type of carbohydrate. Cats need carbohydrates, but only very little. The addition of these extra carbohydrate sources make the % much higher than what a cat needs. Cats are not equipped to digest high amounts of carbs. These types of ingredients are mainly in cat food because they are great binders, they bind the food together effectively.

Corn based ingredients – Corn, especially, is hard to digest and a source of allergies, and health problems. Corn starch, while not corn, is corn based and is an unneeded source of carbohydrates. Protein (corn gluten) from corn is not appropriate as cats are carnivores. Corn based ingredients should be avoided if possible.

Grains – Grains are of poor nutritonal value for cats. Cats cannot digest grains easily. They are in cat foods as a filler ingredient and filler only. Wheat, corn, corn flour, flour, white rice, ground rice, barley, brewer's rice, etc. fall into this category. Ingredients such as wheat gluten and corn gluten also fall into this category as these ingredients originate from grains.

Non-Meat Protein – This refers to protein extracted particularly from non-meat sources, this includes pea and potato protein amongst others. These ingredients have a low biological value. The protein from these sources simply cannot be used effectively by cats, as this protein lacks essential amino acids the cat needs.

Fiber – The jury is still out as to whether ingredients like pea and potato fiber, beet pulp (which doesn't contain the sugar) are bad or good. They are bolded here just to quickly point out both sides of the story. On one hand, the argument can be made that these are cheap fiber sources that do more harm than good. On the other hand, fiber (both insoluble and soluble, fermentable and non-fermentable) has many benefits that shouldn't be overlooked. Too much of one type of fiber is where problems may occur. Each cat reacts differently.

Egg/Egg product – The biggest concern regarding egg ingredients is the quality of eggs used in pet food formulas. Usually it is egg waste. Unless otherwise stated by the company as 'food fit for human consumption.'

Fish/Seafood - Fish have elevated levels of mercury. Feeding a cat fish every now and then is okay. Long term exposure to fish will cause health problems. Also, the majority of the time fish used for pet food is rank and of poor quality. Unless otherwise stated by the company as 'food fit for human consumption'. This applies to seafood as well.

Added Coloring – Sometimes known as artificial coloring. Certain colors, such as ‘Red #3’ are cancerous and are banned from uses in human products. Iron Oxide and Titanium Dioxide also fall into the added color category.

Guar Gum - A less harmful thickening agent used in cat food. Still, interferes with protein absorption and is known to cause GI upset.

Menadione Sodium Bisulfite Complex/Menadione Dimethylpyrimidinol Bisulfite – A man-made form of Vitamin K. There are concerns over toxicity relating to this ingredient in cat food.

Zinc Oxide – Artificially produced source of zinc more often seen in non-food materials. This includes rubber, paints, creams, and batteries. Poisoning due to ingesting too much zinc oxide will occur; present in cat food in safe amounts. Many people don't like to see this ingredient in cat food.

Copper Sulfate – Is an irritant and is linked to copper toxicity. Many do not like the presence of this ingredient in cat food because it has many other uses. It can be found in the leather, wood, battery, ink, paint, and metal industries.

Pork Liver – A nutritious organ meat coming from pork, which refers to pigs.

Wheat Flour -Powder made from grinding wheat. Cats do not get much nutritional value from wheat flour.

Soy Protein Isolate -The protein extracted from soybeans. Isolate is more pure than concentrate as isolate has both carbohydrates and fiber removed, making this ingredient all protein.

Ingredients to Point Out

Non-Meat Protein – This refers to protein extracted particularly from non-meat sources, this includes pea and potato protein amongst others. These ingredients have a low biological value. The protein from these sources simply cannot be used effectively by cats, as this protein lacks essential amino acids the cat needs.

Gluten – Gluten is the protein that is found in many different types of grains, including wheat, rye, and barley. Gluten is a protein source. Cats simply cannot digest gluten and use it effectively in their bodies. They need protein from a meat source.

Starch – This includes pea, potato, tapioca starch (flour). Starch is a type of carbohydrate. Cats need carbohydrates, but only very little. The addition of these extra carbohydrate sources make the % much higher than what a cat needs. Cats are not equipped to digest high amounts of carbs. These types of ingredients are mainly in cat food because they are great binders, they bind the food together effectively.

Egg/Egg product – The biggest concern regarding egg ingredients is the quality of eggs used in pet food formulas. Usually it is egg waste. Unless otherwise stated by the company as 'food fit for human consumption.'

Fiber – The jury is still out as to whether ingredients like pea and potato fiber, beet pulp (which doesn't contain the sugar) are bad or good. They are bolded here just to quickly point out both sides of the story. On one hand, the argument can be made that these are cheap fiber sources that do more harm than good. On the other hand, fiber (both insoluble and soluble, fermentable and non-fermentable) has many benefits that shouldn't be overlooked. Too much of one type of fiber is where problems may occur.

Guar Gum - A less harmful thickening agent used in cat food. Still, interferes with protein absorption and is known to cause GI upset.

Caramel (Color) - Just 'caramel' is added to enhance the flavor of the food. Caramel is basically sugar. Cats cannot taste sweets. An ingredient that has no business in cat food. A low quality ingredient.
It could also mean caramel coloring, if that is the case it would be under the term 'added coloring.' Caramel color alters the appearance of the food and is potentially harzardous as it is possibly carcinogenic.

Zinc Oxide – Artificially produced source of zinc more often seen in non-food materials. This includes rubber, paints, creams, and batteries. Poisoning due to ingesting too much zinc oxide will occur; present in cat food in safe amounts. Many people don't like to see this ingredient in cat food.

Sodium Selenite - Many cat owners are concerned about this ingredient. It is a cheaper form of selenium and is linked with selenium toxicity. This is because ingredients such as fish, meat, and grains already contain selenium naturally. Therefore the addition of sodium selenite just adds more selenium to the formula. For what it is worth, a study has shown sodium selenite is no more harmful than natural sources of selenium.

Zinc Oxide – Artificially produced source of zinc more often seen in non-food materials. This includes rubber, paints, creams, and batteries. Poisoning due to ingesting too much zinc oxide will occur; present in cat food in safe amounts. Many people don't like to see this ingredient in cat food.

Copper Sulfate – Is an irritant and is linked to copper toxicity. Many do not like the presence of this ingredient in cat food because it has many other uses. It can be found in the leather, wood, battery, ink, paint, and metal industries.

Adult 7+ Tender Chicken Dinner

 

Ingredients

Water, Chicken, Pork Liver, Wheat Flour, Wheat Gluten, Dextrose, Modified Rice Starch, Oat Fiber, Egg Whites, Chicken Liver Flavor, Soybean Oil, Titanium Dioxide color, Dicalcium Phosphate, Potassium Chloride, Fish Oil, Choline Chloride, L-Lysine, Calcium Carbonate, vitamins (Vitamin E Supplement, Thiamine Mononitrate, Ascorbic Acid (source of Vitamin C), Niacin Supplement, Pyridoxine Hydrochloride, Calcium Pantothenate, Vitamin B12 Supplement, Riboflavin Supplement, Biotin, Vitamin D3 Supplement, Folic Acid), Iodized Salt, Taurine, Guar Gum, Calcium Chloride, Caramel color, minerals (Zinc Oxide, Ferrous Sulfate, Copper Sulfate, Manganous Oxide, Calcium Iodate), Beta-Carotene.

First 5 ingredients

Water - Used to add moisture to the formula. In canned foods, moisture percentage can be up to 80%.

Chicken – Meat, skin, and bone of chicken. About 70% moisture therefore is always seen near the top of ingredients lists. After cooking, the chicken loses most of its moisture as well as protein. A common ingredient found in cat food.

Pork Liver – A nutritious organ meat coming from pork, which refers to pigs.

Wheat Flour -Powder made from grinding wheat. Cats do not get much nutritional value from wheat flour.

Wheat Gluten – Gluten that has been extracted from wheat. A plant based protein, so mostly nutritionally useless in cat food.

Ingredients to Point Out

Grains – Grains are of poor nutritonal value for cats. Cats cannot digest grains easily. They are in cat foods as a filler ingredient and filler only. Wheat, corn, corn flour, flour, white rice, ground rice, barley, brewer's rice, etc. fall into this category. Ingredients such as wheat gluten and corn gluten also fall into this category as these ingredients originate from grains.

Gluten – Gluten is the protein that is found in many different types of grains, including wheat, rye, and barley. Gluten is a protein source. Cats simply cannot digest gluten and use it effectively in their bodies. They need protein from a meat source.

Starch – This includes pea, potato, tapioca starch (flour). Starch is a type of carbohydrate. Cats need carbohydrates, but only very little. The addition of these extra carbohydrate sources make the % much higher than what a cat needs. Cats are not equipped to digest high amounts of carbs. These types of ingredients are mainly in cat food because they are great binders, they bind the food together effectively.

Fiber – The jury is still out as to whether ingredients like pea and potato fiber, beet pulp (which doesn't contain the sugar) are bad or good. They are bolded here just to quickly point out both sides of the story. On one hand, the argument can be made that these are cheap fiber sources that do more harm than good. On the other hand, fiber (both insoluble and soluble, fermentable and non-fermentable) has many benefits that shouldn't be overlooked. Too much of one type of fiber is where problems may occur. Each cat reacts differently.

Egg/Egg product – The biggest concern regarding egg ingredients is the quality of eggs used in pet food formulas. Usually it is egg waste. Unless otherwise stated by the company as 'food fit for human consumption.'

Added Coloring – Sometimes known as artificial coloring. Certain colors, such as ‘Red #3’ are cancerous and are banned from uses in human products. Iron Oxide and Titanium Dioxide also fall into the added color category.

Guar Gum - A less harmful thickening agent used in cat food. Still, interferes with protein absorption and is known to cause GI upset.

Caramel (Color) - Just 'caramel' is added to enhance the flavor of the food. Caramel is basically sugar. Cats cannot taste sweets. An ingredient that has no business in cat food. A low quality ingredient.
It could also mean caramel coloring, if that is the case it would be under the term 'added coloring.' Caramel color alters the appearance of the food and is potentially harzardous as it is possibly carcinogenic.

Zinc Oxide – Artificially produced source of zinc more often seen in non-food materials. This includes rubber, paints, creams, and batteries. Poisoning due to ingesting too much zinc oxide will occur; present in cat food in safe amounts. Many people don't like to see this ingredient in cat food.

Copper Sulfate – Is an irritant and is linked to copper toxicity. Many do not like the presence of this ingredient in cat food because it has many other uses. It can be found in the leather, wood, battery, ink, paint, and metal industries.

First 5 ingredients

Water - Used to add moisture to the formula. In canned foods, moisture percentage can be up to 80%.

Tuna – A species of fish. Tuna is a great protein source.

Wheat Flour -Powder made from grinding wheat. Cats do not get much nutritional value from wheat flour.

Ingredients to Point Out

Fish/Seafood - Fish have elevated levels of mercury. Feeding a cat fish every now and then is okay. Long term exposure to fish will cause health problems. Also, the majority of the time fish used for pet food is rank and of poor quality. Unless otherwise stated by the company as 'food fit for human consumption'. This applies to seafood as well.

Menadione Sodium Bisulfite Complex/Menadione Dimethylpyrimidinol Bisulfite – A man-made form of Vitamin K. There are concerns over toxicity relating to this ingredient in cat food.

Guar Gum - A less harmful thickening agent used in cat food. Still, interferes with protein absorption and is known to cause GI upset.
