Why Cats Don't Drink Enough — and How to Protect Their Kidneys

Cats descend from desert animals, and it shows — they're notoriously poor drinkers. The trouble is that low water intake puts strain on the kidneys and bladder over time, and kidney disease is one of the most common problems in older cats. The fix is refreshingly simple: help them drink more.

Why hydration matters so much

Chronic dehydration contributes to urinary crystals, painful blockages (especially in male cats, which can be a life-threatening emergency) and long-term kidney strain. Good hydration is one of the easiest ways to protect your cat.

Getting your cat to drink more

• Try a pet water fountain. Many cats prefer running water and will drink far more from a fountain than a still bowl.
• Offer multiple water stations around the home, away from food and litter trays.
• Use wide, shallow bowls — cats dislike their whiskers touching the sides.
• Add wet food to the diet. Tinned or pouch food is mostly water and is a brilliant way to sneak in hydration.
• Keep water fresh and clean — cats are fussy for good reason.

Warning signs to watch

• Drinking or urinating noticeably more than usual.
• Straining in the litter tray, or crying while urinating (see a vet urgently — a blockage is an emergency).
• Weight loss, poor appetite, or a scruffy coat in an older cat.

Prevention through check-ups

For cats over about seven, a yearly check-up with basic blood and urine tests can catch kidney changes early — when there's the most you can do about it. A little water today buys a lot of health tomorrow.
