Why Does My Cat Vomit

Cats do tend to vomit and if this only happens occasionally such as a couple of times a month there is no cause for concern. However, if your cat vomits more often, such as on a daily basis, you should probably discuss it with your veterinarian. There are numerous reasons why a cat will vomit, so let’s take a look.

So why does my cat vomit?

In most cases the reasons are easily explained and are not of concern. Reasons may include:

Overeating: sometimes your cat will gorge on food and will regurgitate directly after eating. In this situation, the food that has been regurgitated is still in undigested form and it can present in a tubular shape or just in a small mound.

Eating grass or other non food items: Eating grass often makes cats vomit and some people believe this is the reason that they do it. If you look at the vomit you may notice a foreign body such as a plastic item like a rubber band or hair grip or anything else that the cat has mistakenly eaten.

Hairballs: Cats spend a long time grooming so can often throw up hair balls. Not all cats do this because sometimes the hairball can pass through the digestive system. If your cat throws up a hairball it will look like hair mixed with vomit.

Food allergies: A very common cause of vomiting is when a cat has a food allergy and these are more common than you may think.

For example some cats are allergic to milk and dairy products so although most cats will love a saucer of milk, it can cause them to vomit.  Some cats are allergic to meat products, others to fish so it is important to find out by monitoring your cats diet and habits.

Many people asking the question why does my cat vomit can often find the answer with a neighbor.  If you know your cat has a food allergy you may find that your neighbours are feeding your cat and may be inadvertently making your cat vomit.

Constipation: it can be hard to tell if your cat is constipated if you cat is allowed out of your house because they do tend to keep their poo private. However if you notice your cat hasn’t gone out or there are hard pellets in the dirt box, your cat could be constipated. This often leads in turn to vomiting because the cat feels bloated and bunged up.

If you know your cat is suffering from constipation there are plenty of OTC laxatives designed for cat constipation.

Why does my cat vomit? If you have ruled out all the possible reasons why your cat is vomiting and it is happening on a regular basis, you should seek advice from your veterinarian. It could be a sign of an underlying health condition especially if you notice blood in the vomit or your cat is lethargic, losing weight or is off their food.
