Hairballs act as the reason for clear liquid vomiting. As cats are clean animals and can groom themselves, small structures on their tongue become loose and then gulped down.

When your cat throws out clear liquid, it is their way to spit out hairballs outside their stomach. The best way to avoid this situation is to groom your cat regularly and offer them a high fiber intake.


Cats can vomit due to various reasons for an upset stomach. Like in humans, a cat’s stomach also produces various gastric juices and, importantly, hydrochloric acid to digest their food. If your cat skips the meal for any reason, or if not fed properly, then high levels of acid and juice can irritate the cat’s stomach and cause them to vomit.
