Reasons that Cats Throw Up

There are quite a few possible explanations for your kitty throwing up that you’ll want to be aware of.

1. They Ate Something They Cannot Digest

Sometimes a cat will throw up if it eats something that it cannot properly digest, such as a piece of plastic from a toy. The big problem with your cat eating these things is that they could get an intestinal obstruction. This can actually be fatal, so you need to take it seriously.

If you notice that your cat has eaten a piece of plastic, paper or other things they aren’t meant to digest, you’ll need to keep a close eye on them. If your cat develops persistent vomiting, you should get them to the vet right away. The longer you wait to do this, the more dangerous the situation becomes.

2. Your Cat Ate Too Much

It’s also possible that your cat is throwing up because it ate too much, or too quickly. This is actually pretty common with these animals, and it’s usually not a big deal. You just have to let your cat vomit and give its stomach a rest.

3. They Have an Infection

Sometimes a cat will throw up if it has a bacterial or fungal infection. This is pretty common with bacterial infections acquired from eating spoiled meat. Salmonella is a type of bacteria that can cause severe nausea, vomiting and diarrhea.

You might also notice that your cat is coughing and has a lack of appetite. If you think that they might have some sort of infection, you’ll need to get it treated right away. The longer you ignore the infection, the worse it will become.

4. Parasites

Certain parasites that burrow into a cat’s intestines, such as whipworms and hookworms, can cause the animal to throw up. These internal parasites can cause a lot of harm to your kitty, but they are usually pretty easy to treat. Your veterinarian can prescribe medication that is specifically made to kill these types of parasites.

A cat that has internal parasites might also exhibit a number of other symptoms, including diarrhea, lack of appetite, and lethargic behavior. The last thing you want to do is to ignore these symptoms. The fact is that it doesn’t take very long for these parasites to do irreversible damage to your cat’s overall health.

5. Allergies

If your cat consumes food that it is allergic to, they might start vomiting. There are certain foods that a lot of cats are allergic to, including beef, eggs, and even milk. It is not a good idea to give your cat anything that contains lactose, as they might have a negative reaction.
