Is Pizza Safe For Cats?

Cats enjoy a wide variety of food which isn’t their own cat food, but have you ever wondered, can a cat eat pizza? You may be surprised to know that most kittens and even some adult cats enjoy pizza, especially the kind loaded with cheese and meats. While cheese and seasoned meat will not harm your cat in small amounts, there are some ingredients found on most pizzas that will.

Ingredients Harmful to Cats

Garlic is the most harmful ingredient that you’ll find in pizza. It’s poisonous to both cats and dogs. Most pizza will have garlic even if you didn’t order a garlic pizza, so be careful.

Next, perhaps the most common ingredient on a pizza, tomato. The leaves and stems of a tomato plant can lead to death, and eating unripened tomatoes (green ones) are highly poisonous. The good news is that most of the harmful chemicals found in tomatoes are gone when the tomato has been fully ripened but you have to remember that cats are much, much smaller than us. Cooking also dissolves most of the poisons as well. Sauce may not be poisonous in small amounts but it can cause intestinal distress and in high doses, can be poisonous.

Don’t forget onions!

Garlic and onions are both in the same “family” and both are extremely toxic. Other members of the onion family include chives, leeks, and shallots.

What About the Fat Content?

You already know pizza is very fattening, but this doesn’t mean your cat knows or even cares! Most pizzas are very high in fat and will not only cause your cat to pile on the pounds, but these particular fats increase the chances of feline diabetes. The fats in the cheeses, oils, and meats are the worst but don’t think for one second that the crust is okay!

Yeast is something that cats have a hard time digesting. While cooked bread and dough are considered to be harmless to your cat, raw yeast can kill a cat in a matter of hours. Most cats will not eat pizza dough uncooked or even cooked unless it’s loaded with butter and oil. My one cat LOVES the smell of pizza and garlic bread and I have caught him eating both in the past so be very careful if your cat jumps up on your tables and counter spaces. Never leave pizza sitting out. Put it away as soon as you are done and throw away any unwanted leftovers in a sealed bag.

Cute but Deadly

While the internet will mostly agree, cats stealing pizza is absolutely adorable, it is far too dangerous to be laughing and aww’ing at. Do not encourage your cat to eat pizza. If your cat accidentally gets hold of some pizza, do not panic. Make sure they drink plenty of water and keep an eye on them for a few days to make sure they are not sick. If your cat ate pizza and becomes poisoned, you will know within 6 hours, as symptoms such as vomiting, crying, diarrhea, panting, and fatigue will start.

Take no risk with your cat, it’s not worth it. You control what they eat, so keep them healthy!

I gave my cat the slightest bit of Pizza Hut crust and he did not eat it. He just sat their licking it and then went back to playing with his catnip toys


Ok, i gave my cat i TINY piece of pizza. By tiny, i mean the size of my fingernail. Will he be ok???


my cat ate pizza once

it disappered so uh


So, we can feed our cats pizza, but we should only give them VERY small amounts because the…..
Bread is hard to digest
Tomato can be dangerous
Garlic is very poisonus, so you should double, no triple check so there is no garlic at all.

Is that everything?
Eh, i just give my cat a litttle bit of the ham pork meat things and sometimes shrimp if i have any.

Kit Kat

I never knew that cats would have a hard time digesting yeast and can also be dangerous for their lives. I guess I would have to enjoy a pizza for myself. This just made me curious because I plan to eat out on my own this weekend just to reward myself for working hard, and I thought of bringing my cat with me since it is the only companion I have these days. This has made me realize that it is not advisable to feed it with pizza.

Thanks for helping me understand that the garlic is a poisonous food for both cats and dogs. With that in mind, I will make sure to ask the chef of the pizza place to remove those. Actually, I also don’t like garlic, so it will also benefit me. I am researching about this since I wanted to celebrate the 2nd birthday of my cat in a pizza place for a twist.


why would you take a cat to a pizza place? I would take my baby to a sushi resturant.

Why not?


I was at a campfire & in the middle of nowhere there were these two small cats. One looked only about 2-5 months old & the other looked maybe 1-2 yrs. We had nothing with us but Costco pizza. I shredded up some slices & put them on a plate & they were eating a lot of it. I’m worried about these feral kitties will they be ok in the woods? I have no idea how they got there but we couldn’t get close without them running. Have I poisoned them??? 🙁
