Cats are naturally very clean creatures, and they spend a significant portion of their day grooming. Tiny hook-like structures on your cat's tongue snag loose and dead hair when they groom themselves, and the hair is then ingested.
The bulk of hair moves through the digestive system without any issues, however occasionally hair becomes stuck in the stomach and forms a hairball.
Your cat may vomit up clear liquid when your cat's feeding schedule changes, if your cat skips a meal, or if your cat feeds later than usual.
Similar to humans, cats also create hydrochloric acid and other gastric secretions in their stomachs to help in food digestion.
The buildup of juice and acid, however, can irritate the stomach and cause your cat to vomit if they skip a meal or are not fed on time.
It's likely that your cat has irritated their stomach with anything they've eaten if they tend to get into things they shouldn't. When this occurs, in addition to seeing vomiting blood and/or bile, you might also witness vomiting clear liquid.
Additionally, your cat can be displaying a decline in appetite, a downcast demeanour, lethargy, or dehydration. If your cat is throwing up due to gastritis, your veterinarian will know just what to do.
