Vet advice on how much water cats should drink
Cats can be fussy when it comes to drinking water. Some prefer to drink from puddles outside or straight from the kitchen tap. Others may seem to not drink much at all.
Cats can also drink different amounts depending on their diet. “If your cat is eating wet food, they are likely getting much of their water intake from their diet,” says vet Sarah Elliot, “whereas cats that mainly have a dry diet will often drink more water.”
“The important thing is to always make sure your cat has access to fresh, clean water, so they can drink whenever they want to.
“Place bowls of water in various locations around the home, so water is always within easy reach. Also, cats prefer it when their water is kept at a distance from their food bowl and litter tray, to avoid cross-contamination. They will usually drink more if you keep everything separate.”

How to measure how much your cat drinks
To measure how much water your cat drinks each day:
- Fill a measuring jug with water at the beginning of the day and make a note of the amount of water.
- Put this amount of water into your cat’s water bowls.
- At the end of the day, pour the leftover water back into the measuring jug and make a note of the amount.
- Subtract the amount of leftover water from the amount you recorded at the beginning of the day. This will tell you how much your cat has drunk.
