Can cats eat pizza?

Sometimes — with caution
Same — too many problematic ingredients.
The short answer
Sometimes — with caution — cats should only have small amounts of pizza. Avoid Italian flatbread with toppings.
Remember: cats are obligate carnivores. They derive almost all their nutrition from animal protein, so even "safe" plant foods are treats — not staples.
Why be careful
Same — too many problematic ingredients.

Kitten safety
Generally avoid feeding pizza to kittens. Their digestive systems are still developing and they're more sensitive to changes in diet, fat, sodium, and lactose than adults. If you've already given some, watch for vomiting, diarrhea, or lethargy and contact your vet if any appear.
What to do if your cat ate pizza
- Note how much was eaten and when. A small amount is rarely an emergency, but a large quantity may need vet attention.
- Watch for symptoms over the next 12–24 hours: vomiting, diarrhea, lethargy, loss of appetite, or changes in drinking/urination.
- Provide fresh water and skip the next meal if your pet seems unsettled — let their stomach calm down.
- Call your vet if symptoms appear or persist beyond 24 hours, or if the amount eaten was significant.
