How much coconut can a cat eat?
Treats of every kind should stay under 10% of a cat's daily calories. Here is that daily treat budget by size, and how much coconut it buys if coconut is the only treat that day. Coconut has about 354 kcal per 100 g; 1 piece (2" x 2" x 1/2") (45 g) is about 159 kcal.
| Cat size | Daily treat budget | Max coconut a day |
|---|---|---|
| Small cat (6 lb) | 18 kcal | 5 g (an eighth of piece (2" x 2" x 1/2")) |
| Average cat (10 lb) | 26 kcal | 7 g (a quarter of piece (2" x 2" x 1/2")) |
| Large cat (14 lb) | 34 kcal | 9 g (a quarter of piece (2" x 2" x 1/2")) |

Other fruit: quick answers
| Food | Verdict | Short answer |
|---|---|---|
| Citrus fruit | Avoid | Best avoided. Citrus oils and acid can irritate, though a small taste usually only upsets the stomach. |
| Bananas | Small amounts | A small piece now and then. Bananas are safe but high in sugar. |
| Peaches | Small amounts | A small piece of peeled flesh is fine. Never the pit, stem or leaves. |
| Watermelon | Small amounts | A little seedless flesh is fine. Remove the rind and seeds. |
| Grapes | Toxic | No. Grapes are on vets' do-not-feed lists for pets. |
| Raisins | Toxic | No. Raisins are on vets' toxic lists for pets, just like grapes. |
Rules for any new food
- Plain is the rule: no salt, butter, oil, onion, garlic, sugar or sweeteners. Most of the danger in human food comes from what is added to it.
- Keep all treats under 10% of your cat's daily calories . The rest should come from a complete cat food.
- Check labels for onion and garlic powder, which turn up in stock, gravy, baby food and seasoned meat.
- If your cat has a health condition, such as diabetes, kidney disease or a sensitive stomach, ask your vet before adding any new food.
