Changes in a cat's drinking habits are worth paying attention to. Drinking more water can happen for ordinary reasons, such as warmer weather or a diet change, but persistent or marked changes can also accompany health problems.
A cat drinking more water can have simple explanations or may warrant veterinary attention. Learn what changes to watch and when to call your vet.
Normal Reasons Drinking May Increase
- Hotter weather or a warmer indoor environment.
- A change from wet food to dry food.
- More activity than usual.
- Increased access to fresh water.
When to Pay Closer Attention
If increased thirst continues or occurs together with frequent urination, weight loss, appetite changes, vomiting, weakness, or other unusual behavior, contact your veterinarian. Increased thirst can occur with several medical conditions, so the drinking change alone cannot identify a cause.
Track the Change
Note when the change started, whether the diet changed, how often the water is being refilled, and any other symptoms. This information can help your veterinarian assess the situation.
Support Good Hydration
Keep clean water available at all times. If your cat prefers moving water, a fountain can be one option, but it should be cleaned regularly.
