Cats are obligate carnivores, and it changes the shopping

Unlike dogs, cats have absolute dietary requirements that can only practically be met from animal tissue. Two matter most: taurine, an amino acid whose deficiency causes heart disease and blindness, and pre-formed vitamin A, which cats cannot make from plant precursors.

The practical consequence is that a cat cannot be fed a vegetarian diet safely without careful veterinary formulation, and that animal protein content is the first thing to look at on a label rather than a marketing claim.

Read the AAFCO statement before the ingredients

Find the nutritional adequacy statement. It tells you the life stage the food is formulated for and whether that was established by feeding trials or by formulation to a profile. "Complete and balanced for maintenance" is not suitable for kittens; "all life stages" meets the more demanding growth standard.

Anything without an adequacy statement is a complementary food or treat however it is marketed — including many of the appealing pouches sold alongside complete diets.

Wet, dry, or both

This is the decision with the largest health consequences.

Wet food is roughly 70–80% moisture. Cats have a weak thirst drive and are poor at compensating for a dry diet by drinking, so wet food meaningfully increases total water intake. That matters because urinary tract disease and chronic kidney disease are among the most common feline problems. Wet food is also typically higher in protein and lower in carbohydrate.

Dry food is cheaper, more convenient, keeps once opened, and suits free-feeding and puzzle feeders. It is also easy to overfeed, because the calories are dense.

Many vets suggest including wet food in the diet for hydration reasons, with dry available or used in enrichment feeders. The combination suits most households better than either alone.

What ingredient lists do and do not tell you

Ingredients are listed by pre-cooking weight, so fresh chicken — around 70% water — appears high while contributing less protein than its position suggests. Chicken meal, already dried, looks less appealing and often delivers more.

Watch for ingredient splitting, where peas, pea protein and pea fibre are listed separately and collectively outweigh the named meat. The guaranteed analysis and, better still, calories per can or cup, tell you more than the order of the list.

Grain-free is heavily marketed and rarely necessary: true grain allergy in cats is uncommon, and protein sources are more frequent allergens than cereals.

Feeding patterns and weight

Obesity is the most common preventable health problem in housecats, and free-feeding dry food is the usual route to it. Measured meals — two or more a day — give you control and, importantly, let you notice immediately when a cat goes off its food, which is often the first sign of illness.

Judge portions by body condition rather than the bag: you should feel ribs easily without pressing, and see a waist from above. Bag guidelines are calculated for an average active cat and commonly overestimate for a neutered indoor one.

Puzzle feeders and food-dispensing toys are worth using for indoor cats. Working for food is closer to natural behaviour and slows down fast eaters.

Changing food

Cats are neophobic about food and can be genuinely stubborn. Transition over seven to ten days, increasing the new proportion gradually. An abrupt switch commonly causes both refusal and digestive upset.

One warning that matters: a cat that stops eating entirely needs veterinary attention quickly. Cats that go without food for more than a day or two — particularly overweight cats — can develop hepatic lipidosis, a serious liver condition. Never attempt to starve a fussy cat into accepting a new food.

Formulations, ingredient sourcing and manufacturing arrangements change over time. Confirm current details with the manufacturer, and discuss diet with your vet for any cat with a health condition or on a prescription diet.
