Can cats eat pizza crust?

Do you love pizza as much as your cat does? You might think that since both of you enjoy this cheesy dish, your kitty would be just as happy nibbling on a piece of pizza crust as you are.

While some experts believe that cats can eat a bit of pizza crust, others think that pizza does not fulfill the vital feline nutritional needs.

But is that really the best idea? Here’s what you need to know about feeding your cat pizza crust.

What do cats usually eat?

Before answering this question, it is important to know what kind of animals cats are. Cats are obligate carnivores. Obligate means that their diet is the only factor that determines whether or not they will survive.

Cats’ natural prey consists of small mammals, such as mice and rabbits, but also birds and insects. As a result, cats have very specific dietary needs to make sure they get all the nutrients they need from their food.

Cats must eat meat in order to survive.

Cats get the majority of their nutrients from protein, including essential amino acids and fatty acids.

This is why meat-based proteins are very important in your kitty’s diet. Cats also require certain specific vitamins, minerals, and nutrients that can only be found in animal tissues. That’s why you should always feed your cat food that is specially formulated for carnivores.

6 Ways to feed pizza crust to your cat

Do not overfeed

If you love your cat as much as you enjoy a cheesy pizza, then it’s fine to give her a slice of crust now and then. Just don’t make it a daily routine. Too many carbs can cause different kinds of health problems in cats like obesity, fatty liver disease, and diabetes.

  • If your kitty likes crust, you can give her a slice every once in a while.
  • When your cat wants to share some pizza with you, let her lick the cheese off your toppings before you eat them. This way, she’ll get the flavor she likes without eating any of the carbs in the crust.

Make sure the pizza crust is fully cooked

Raw dough is unhealthy for cats because it can expand inside their digestive system and cause dangerous intestinal obstructions.

Cooked dough, on the other hand, is perfectly fine for your cat to eat. You can even give her a small piece of cooked pizza crust every once in a while. It is safe to feed your kitty-cooked flour products as long as they are fully cooked.

Always give your cat a small piece of raw meat, fish, or eggs as an occasional treat.

It is better to give your kitty some healthy pieces of meat for treats if she really wants something crunchy or chewy to nibble on. This way you will make sure she gets the nutrients she needs without giving too much pizza crust.

Soften the crust

If you want to give your kitty a piece of pizza crust, but don’t want her to eat too many carbs, soften it up in some warm water before feeding it to her.

This way she’ll feel like she’s eating something crunchy without getting any of the possible negative health effects that come with eating crackers or chips.

Spices are a big no-no

Don’t feed your kitty any spices or seasonings when you’re feeding her pizza crust. Spices are not only bad for your cat’s tummy, but they might also be dangerous to her health in general.

A slice of plain cheese pizza is probably one of the better options for a healthy snack if you want to share some food with your kitty.

If you really want to feed your kitty a bit of pizza, make sure that it is plain and doesn’t contain anything that could be harmful to her.

No onion. No garlic.

Onions and garlic are harmful to your cat’s health, so keep these ingredients away from her.

If you want to give your kitty a real taste of pizza, make sure that it doesn’t contain onions or garlic. These two items are bad for cats because they can cause gastrointestinal problems like vomiting and diarrhea, as well as damage red blood cells.

Avoid oregano

Oregano is usually safe for people to eat, but it can cause problems in cats.

Just like spices, oregano has the potential to upset your kitty’s stomach or make her very ill. To be on the safe side, don’t use it when you’re cooking food for your cat.

Hazards of overfeeding pizza crust to your cat

Digestive tract problems

Don’t feed your kitty raw dough products because it can expand inside her digestive tract and cause dangerous intestinal obstructions.

The crust of the pizza is the only part that the majority of cats seem to like. They enjoy eating bread, but if you try feeding them too much of it or even just offer them a slice, they might start throwing up.

Too much bread can cause digestive problems in your kitty, so keep an eye on her diet afterward.

Gastrointestinal Upset

Baking powder and yeast in the dough can cause gastrointestinal upset when eaten by your cat.

Pizza crust contains baking powder and yeast that can cause your cat to experience an upset stomach, vomiting, or diarrhea when she eats too much of it.  

Especially, oregano is lethal for cats.

Oregano is not safe for cats.

If you don’t want to hurt your cat, never feed her any oregano because it can make her seriously ill. It can cause gastrointestinal problems like vomiting and diarrhea, as well as damage red blood cells. Its oils are also toxic to the liver and kidneys.

Fatty Liver Disease

A high-carb diet is not good for your kitty.

Carbohydrates, such as flour and grains in the crust of a pizza, can lead to fatty liver disease when overfed.

A high-carb diet is one of the leading causes of feline fatty liver disease. If cats eat too many carbs during a short time or on a regular basis, they may experience liver failure.
