Feeding Your Cat

Nutrition Considerations

Cats are obligate carnivores and benefit from diets high in animal-based protein and moisture.

The current recommendation is that all cats ideally eat a diet of 100% canned food. There is no nutritional or health benefit to feeding dry food, and dry-food diets are associated with many common health concerns in cats.

• Moisture matters. Canned food is approximately 70% water and helps meet a cat’s natural hydration needs. Cats are designed to obtain most of their fluids from prey, not from drinking separately.
• More appropriate protein. Canned diets generally contain a higher proportion of animal-based protein and fewer plant-derived fillers.
• Lower calorie density. Because of its high moisture content, canned food is significantly lower in calories per volume than dry food, even many “weight loss” dry formulas.

When selecting canned foods, consider choosing options without carrageenan. Carrageenan is a thickening agent used in some canned diets and has been associated with gastrointestinal inflammation in laboratory studies. While research is ongoing, many veterinarians recommend avoiding it when possible, especially for cats with sensitive stomachs.

How Much to Feed

An average adult cat of healthy weight and moderate activity level requires approximately 200 calories per day. Individual needs may be higher or lower depending on age, body condition, health status, and activity level.

Check the calorie content listed on the food label (kcal per can or per cup) to calculate appropriate portions.

• Average adult cat (canned only): Approximately 5–6 oz per day, divided into multiple meals.
• Adult cat eating canned and dry: Approximately 3 oz canned plus a small measured portion of dry food daily.
• Growing kittens: Free access or multiple generous meals (3–4 per day minimum) until about 7–9 months of age, depending on growth and body condition.

Transitioning to a New Food

If you plan to change your cat’s diet, do so gradually over 7–14 days to prevent digestive upset.

• Days 1–3: 75% current food, 25% new food
• Days 4–7: 50% current food, 50% new food
• Days 8–14: 25% current food, 75% new food
• Then transition fully to the new diet

If decreased appetite, vomiting, or diarrhea occur, slow the transition.

Feeding Schedule

Cats do best with multiple small meals per day rather than unlimited access to food.

Feed at consistent times each day to reduce stress and better monitor appetite and health.

While not recommended, if dry food is part of a cat’s diet, provide measured portions to allow better weight control and appetite monitoring. Free-feeding dry food often leads to overeating and weight gain.

Using Food for Enrichment

Food can provide mental stimulation as well as nutrition.

• Place small portions in different locations to encourage movement.
• Use food-dispensing toys to mimic natural hunting behavior.
• Rotate enrichment tools to maintain interest.

If your cat is new to your home, introduce food puzzles only after the cat is fully settled and eating reliably.

Monitoring Appetite

Know your cat’s normal eating habits. Sudden decreases in appetite can signal stress or medical concerns.

If your cat eats little or nothing for more than 24–48 hours, contact your veterinarian. Overweight cats and young kittens are at greater risk for complications if they stop eating.

Key Takeaway

A moisture-rich, meat-focused diet with measured portions supports long-term health. Consistency, appropriate nutrition, and daily appetite awareness are key.
