No. Croissants are packed with butter and lactose — the wrong package for a cat’s gut.

Why it’s a problem

A croissant is layers of dough and a remarkable amount of butter, combining empty carbohydrate with concentrated milk fat. Most adult cats are lactose intolerant, and a fatty, buttery baked good is a reliable recipe for diarrhea and, in richer cases, pancreatitis.

How to serve it safely

Keep croissants and other butter-rich pastries to yourself, and store them out of counter-surfing range.

Warning signs to watch for

Vomiting, diarrhea, gas and abdominal pain within hours; severe cases show hunched posture and refusal to eat as pancreatitis develops.

When to call the vet

Call your vet if vomiting persists or the cat will not eat for more than a day after a pastry raid.

Common questions

What about a plain croissant corner?

A small piece is unlikely to cause more than mild stomach grumbles in some cats — but there is no version of a croissant that is good for a cat.
