Why is my cat drinking so much water?

AI Answer

A cat that suddenly drinks a lot more water should see a vet. Increased thirst in cats is commonly linked to kidney disease, diabetes or an overactive thyroid (hyperthyroidism), especially in cats over 7.

Other causes: switching from wet to dry food, hot weather, or some medications.

What to do: note how much your cat drinks and pees (bigger litter clumps are a clue), and book a vet visit. Blood and urine tests usually find the cause. Go the same day if your cat is also vomiting, not eating, or very lethargic.
