How much should I feed my pet?
A starting point from the calorie formula vets use, then grams a day for your pet's food.
Then check and adjust
- Every pet is different: the right amount can be up to half more or half less than this. Use it as a start.
- Weigh them every few weeks. Gaining weight: feed a little less. Losing it: a little more.
- You should be able to feel their ribs easily, without seeing them.
- Pregnant, feeding young, poorly, or on a weight-loss plan? Ask your vet how much to feed.
