How Much Should I Feed My Cat? Portions by Weight and Age

Cats are small, so a little extra food each day adds up quickly. Obesity is one of the most common health problems in pet cats, and it raises the risk of diabetes, arthritis and urinary problems. Here is how to feed the right amount. Our pet food calculator can do the maths for you.

How many calories does a cat need?

A typical neutered adult cat needs about 20 calories per pound of body weight per day (around 45 kcal per kg), though this varies. A healthy 4.5 kg (10 lb) cat needs roughly 200 to 250 kcal daily. Kittens need more per kilo while they grow, and less active or senior cats may need less.

Wet or dry food?

Wet food provides water, which helps urinary health, while dry food is convenient and often cheaper. Many owners feed a combination. Always check the calories on the label and count them together. A typical 85 g can of wet food holds about 70 to 100 kcal, while dry food is often 350 to 450 kcal per cup.

How often?

Two to four small meals a day suit most adult cats. Puzzle feeders can add enrichment and slow eating. Leaving a full bowl out all day often leads to overeating.

Signs of a healthy weight

You should feel the ribs with light pressure and see a slight tuck behind the ribs. A sagging belly flap is normal, but a round belly with no waist suggests extra weight.

Weight loss

Never put a cat on a crash diet. Rapid weight loss can cause serious liver disease. Ask your vet for a safe plan.

Treats and water

Limit treats to under about 10 percent of daily calories and always provide fresh water.
