RER = 70 × (kg)^0.75, multiplied by an activity factor for daily energy. Cats do best on multiple small meals or free-choice if weight allows. Wet food is the easier path for hydration. Always weigh your cat the same way at the vet (4 lb of fluff hides 2 lb of fat).

Wet or dry?+
Wet food helps with hydration, which matters for kidney health. Dry food is cheaper and easier to leave out. Most vets recommend a mix unless your cat has specific needs.
