Why Is My Cat Not Eating But Drinking Water?

Published: March 21, 2026

Quick answer: If your cat is drinking water but refusing food, it can be concerning. This behavior often signals discomfort or an underlying issue that needs attention.

Why this happens

Loss of appetite can be caused by stress, changes in environment, or minor digestive upset. Cats may still drink water even if they don’t feel like eating. Tip: check for recent changes in food, location, or routine.

What you can do

Health problems like dental disease, infections, kidney issues, or nausea can reduce appetite while keeping thirst normal. Tip: look for signs like bad breath, drooling, or low energy.

When to worry

If your cat hasn’t eaten for more than 24–48 hours, it can become serious. Rapid weight loss or dehydration risk may follow. Tip: contact a veterinarian if the behavior persists or worsens.

Final thoughts

Occasional appetite loss may resolve quickly, but ongoing refusal to eat should not be ignored. Early attention can prevent more serious health problems.
