How much zucchini for your cat?
Most guides say "a few pieces". Enter your cat's weight and get the actual daily ceiling, worked out from zucchini's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for cats
Plain zucchini is non-toxic for cats and a fine occasional veggie in small amounts.
Zucchini is one of the genuinely excellent vegetables to share with a dog — low in calories, high in water and fibre, and almost impossible to overdo. If you are looking for a treat that helps an overweight dog feel full, this is close to ideal.
How much is safe?
A few slices for a medium dog is a generous treat, and because zucchini is around 95% water it barely registers on the calorie count. That makes it one of the better options for dogs on a diet, where crunch matters more than calories. Cats can have a small cooked piece, though most will decline.
What happens if a cat eats too much?
Very little goes wrong here. Large quantities of any vegetable can cause gas or loose stools, and raw slices should be cut small enough not to be gulped whole by an enthusiastic dog.
How to serve it safely
Wash it, cut off the ends, and slice into rounds or sticks. It can be served raw for crunch or lightly steamed for older dogs — no salt, no oil, no seasoning. Skip zucchini cooked into human dishes, which usually involves garlic and butter.

Frequently asked questions
Raw or cooked?
Both work. Raw keeps more nutrients and gives satisfying crunch; steamed is easier on sensitive stomachs and senior teeth. Never fried or seasoned.
Is the skin ok?
Yes, and most of the fibre is in it. Just wash it well.
