Cats | Nutrition and Feeding
The full content of the "nutrition and feeding" column in the 12-column knowledge tree for cats. Where the original text could not obtain an authoritative figure for a field, it leaves the field blank and states why; this site preserves that as-is and does not fill in numbers on its behalf. The disease column has been published separately as vet/cat-common-diseases and is not duplicated here.
This article is compiled from the cat section of the veterinary encyclopedia. The same symptom calls for different handling in different species, and following another species' approach can be harmful — first confirm which animal you are dealing with.
| Item | Key points |
|---|---|
| Basic positioning | An obligate carnivore: high animal protein, low carbohydrate, with a dietary requirement for taurine / arginine / arachidonic acid / preformed vitamin A / vitamin B12 (see C-1 for details) |
| Food selection criteria | Choose a complete diet that meets recognized nutritional standards and states clearly which life stages it is suitable for; for nutritional principles see the WSAVA Global Nutrition Guidelines (source text line 305 notes that the WSAVA guidelines cover nutrition) and `Small Animal Clinical Nutrition` (source text line 36) |
| Water | Wet food is the most effective way to increase water intake; several water bowls, wide shallow bowls (so the whiskers do not touch the rim), a flowing water fountain, and water placed away from the food bowl |
| Feeding method | Small, frequent meals; use puzzle feeders / hidden food so the cat "works for its food"; in multi-cat homes they must be able to eat separately so you can see who eats how much |
| Calorie control | Energy requirements fall after neutering, so intake must be actively reduced; measure with a cup rather than by eye; count treats within the total calories |
| Weight loss | It must be slow and designed by a veterinarian; rapid weight loss or fasting can trigger hepatic lipidosis |
What owners most often get wrong when feeding
| Mistake | Consequence |
|---|---|
| Long-term feeding of dog food (or using dog food as a stopgap) | Taurine deficiency → dilated cardiomyopathy, retinal degeneration leading to blindness |
| Feeding only fish / large amounts of raw fish | Relative vitamin E deficiency and steatitis; raw fish contains thiaminase → vitamin B1 deficiency with neurological signs; heavy metal accumulation |
| Giving milk | Most adult cats are lactose intolerant → diarrhea |
| Feeding large amounts of liver | Vitamin A toxicity → bony proliferation of the cervical vertebrae and joints, with pain |
| Home-prepared meat diets without a formulation | Calcium-to-phosphorus ratio, taurine and vitamins become comprehensively unbalanced (kittens run into trouble fastest) |
| Raw feeding | Risk of Salmonella / Campylobacter / Toxoplasma, which can also be passed to the family through feces; risk of bone perforation or obstruction |
| Free feeding all day + high-carbohydrate dry food | Obesity → diabetes mellitus, arthritis, anesthetic risk |
| "If it won't eat, just let it go hungry for a few days" | Hepatic lipidosis, with overweight cats at the highest risk |
| Giving human food (allium species, chocolate, grapes and raisins, alcohol, raw dough, xylitol, caffeine-containing items) | See column 10 |
| Switching food without a transition | Food refusal, diarrhea; cats are extremely conservative about dietary change, so change food slowly |

FAQ
- What should I note about the basic positioning of cats?
- An obligate carnivore: high animal protein, low carbohydrate, with a dietary requirement for taurine / arginine / arachidonic acid / preformed vitamin A / vitamin B12 (see C-1 for details). The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.
- What should I note about food selection criteria for cats?
