Why Cats Vomit After Drinking Water

Cats may bring up water after drinking, which can be confusing. The cause can be simple or a sign of a health issue.

How to Tell the Difference

Cats that drink too quickly can regurgitate almost everything they have just swallowed. Regurgitated water is thin, runny, and usually comes back up soon after drinking. In contrast, clear vomit is thicker and stickier because it comes from the digestive tract.

When to Seek Veterinary Care

If a cat vomits after drinking every day or even every week, it is not normal and should be checked by a veterinarian. Frequent vomiting can lead to dehydration and may indicate problems with the kidneys, liver, stomach, pancreas, intestines, or esophagus. A sudden increase in drinking may also signal an underlying health problem. Other warning signs include diarrhea, reduced appetite, tiredness, unusual thirst, or changes in urination.

Common Causes

• Drinking too much water too quickly
• Hairballs, which can bring up water and food at the same time
• Swallowed objects such as broken toys or string
• Parasites, such as roundworms
• Conditions that increase thirst, like diabetes, kidney disease, or hyperthyroidism

Helpful Tips

• A water fountain may encourage slower drinking
• Ice cubes can give cats something to lick slowly during warm weather
• Regular grooming can reduce the amount of loose hair swallowed, though it may not prevent hairballs entirely
• Watch for patterns and changes in drinking habits to distinguish an isolated incident from a potential health issue
