Why is my cat throwing up clear liquid?

To clear up your mind (and your cat’s throat), here are possible reasons as to why your feline friend is throwing up clear liquid:


Hairballs form when your cat grooms excessively using their tongue. By nature, cats like to clean themselves almost all the time, which is why they are very prone to hairballs. 

When your cat’s tongue has accumulated too much hair inside its digestive tract, it will sometimes form into a hairball, which could potentially hurt your cat when in bigger amounts.

Before your cat coughs a hairball, clear liquid comes out of its mouth first. Hairballs are usually not that alarming when in small amounts. However, if you notice that your cat is having difficulty when coughing them out, it’s best to talk to your vet about the best solution for it.

A solution to this problem is to brush your cat properly. When you groom your cat more often, they are less likely to groom themselves and are also less likely to catch loose fur that goes inside their tummies. 

Likewise, you may also find certain cat food in the market that will help keep hairball formation at bay. You can ask your vet about it.

Food & Dietary Changes

New food sensitivity 

On the other hand, if your cat tastes new food for the first time, switching too quickly could also cause this clear liquid vomiting. Always remember that when introducing new food to your pet, make sure to gradually make the change by putting only a little bit of the new food at first.

It should take 1-2 weeks for them to try and adapt to the new food.When changing cat food, you should carefully observe their reaction. If something goes wrong, stop the new food and go back to the old food. 

Eating too quickly & Changes in Routine

When your cat’s regular feeding schedule has been disrupted, there’s a chance that they might throw up clear liquid. To make sure it doesn’t happen; always schedule your cat’s meals properly.

In some cases, a cat eating too quickly could also cause them to vomit clear liquid, which is sometimes accompanied by food. Cats that have intestinal problems or sensitivities tend to do this often, and they have to be taken to a vet for proper advice. 

Sometimes, this could be a sign of stress because of the presence of other cats.The cat will eat faster than usual so it can finish before another cat shows up and competes for the meal. Or it will finish its meal and go to another cat’s bowl to eat more. To avoid this situation if you have more than one cat in your home, separate their bowls and place their bowls far apart. And make sure the eating space is quiet, without too much activity.


Cats, like humans, can also be prone to indigestion. This happens when hydrochloric acid and other gastric juices build up in their stomach. The said buildup happens when your cat is not fed on schedule or as needed. This results in vomiting due to their stomach being irritated by the acids.

Indigestion will make the cat vomit clear liquid, which is sometimes accompanied by white or yellow foam. 

Oftentimes, indigestion happens when your cat takes a large meal all at once, which makes it difficult for their stomach to take all of the food in a single go. Frequently feeding your cat in little amounts throughout the day will help keep indigestion at bay.


A cat that feels nauseous is dehydrated, and looks generally sick might have gastritis if they vomit clear liquid. This liquid is usually accompanied by blood in the worst-case scenario. Gastritis happens when your cat eats something that’s not suitable for its tummy.

When this happens, take your cat to the vet right away because their stomach has been greatly irritated. Veterinarians will assess your cat and take the best course of action to treat their gastritis.


There are many types of parasites that can become a threat to your cat.If your cat is infected with the parasite, it is likely that they will vomit clear liquid. This symptom is accompanied by a dull coat, unusual weight loss, loss of appetite and if you see parasites in their feces.

Maybe your cat has a worm infection and needs deworming. In this case, the veterinary clinic will be the best place for you to get specific results and treatment for your cat


Cats can also get constipation, just like its human owners. Constipated cats also leave behind bloody feces, aside from the nasty vomit. They may also not want to eat much.

Constipation in cats is usually treated with fiber-rich foods, as advised by your vet.

Foreign Objects 

Cats are naturally curious creatures. They like to bite and chew on many things such as pieces of plastic, string, toilet paper, carpets, etc. However, most of the time they only consume very small amounts and pass them out easily with feces. In some cases these foreign objects accumulate and cause them to vomit clear liquid.

This usually happens with kittens when they are still young and curious, where they try things around and explore. To avoid making your cat easily overwhelmed with things and picking up random foreign objects (and mistake them for food), it’s best to let your cat out early. This way, it will be easier for your cat to know which objects to avoid.

You should also regularly clean up and store away small foreign objects that’s reachable by your cats, such as toys, cutlery, and the like.

If the foreign objects cannot be vomited or cleared through the digestive tract, it may become trapped in the intestinal tract. If your cat refuses to eat, vomiting continuously, and appears to be in pain, maybe it needs surgical intervention. In this case you should contact the veterinarian immediately.
