High Fat, Low Carbohydrate

• Basically, some vets recommend feeding your cancerous cat canned food as opposed to dry food, according to Tracie Hotchner's "The Cat Bible."
  
  

Proof in Dogs

• A high-fat, low-carbohydrate diet has been proven to help slow the growth of tumors in dogs.
  
  

Protein

• Protein could help slow the growth of the tumor. Diets high in meat, raw or cooked, will provide the cat with more protein.
  
  

Debate

• This diet has never been proven to effectively slow cancer growth in cats, but some veterinarians still recommend it because of its success in dogs and because of the pitfalls of dry cat food.
  
  

Dry Food

• Dry food is best avoided with cancerous cats, as it can even cause problems in healthy cats. It can dehydrate the cat, make it a finicky eater and hurt the cat's urinary system.
