How Much Water Should a Cat Drink Per Day?

Many cat parents are surprised to learn that cats are naturally poor drinkers. Descended from desert animals, cats often don't feel thirsty until they're already mildly dehydrated — and chronic low water intake is linked to urinary and kidney problems, two of the most common health issues in cats.

So how much water does a cat actually need?

A healthy adult cat needs roughly 50–60 ml of water per kilogram of body weight per day. For a typical 4 kg (9 lb) cat, that's about 200–250 ml daily — around one full cup. Cats on wet food get a good portion of this from their meals, while cats on dry kibble need to drink significantly more.

Signs your cat isn't drinking enough

• Dry or tacky gums
• Lethargy or reduced appetite
• Concentrated, strong-smelling urine
• Skin that doesn't spring back quickly when gently pinched

5 ways to get your cat to drink more

1. Use running water. Cats instinctively prefer moving water — in nature, still water often means unsafe water. A circulating water fountain can dramatically increase daily intake.
2. Keep it fresh and cool. Change water daily and wash bowls to prevent biofilm buildup.
3. Choose the right material. Stainless steel stays cleaner than plastic and doesn't retain odors that put cats off.
4. Place water away from food and litter. Cats prefer separate stations for drinking.
5. Offer multiple water points around the home, especially in multi-cat households.

A quality water fountain ticks the first three boxes at once — running, filtered, fresh water in a hygienic stainless steel basin. If your cat barely touches the water bowl, it's one of the simplest upgrades you can make for their long-term health. 💛
