Cats are typically good at regulating their water intake, but sometimes they may drink more than usual.
If your cat is drinking more than 4 ounces of water per 5 pounds of body weight, or if they are also urinating more frequently, it's a good idea to see a vet.
Offer your cat wet food, which is higher in moisture than dry food
Don't give your cat sugary drinks
If you're concerned about your cat's excessive thirst, it's always best to see a vet. They can rule out any underlying medical conditions and recommend treatment options.
Kidney disease is a common cause of excessive thirst in cats. As the kidneys deteriorate, they are less able to remove waste products from the blood.
Diabetes is another common cause of excessive thirst in cats. When a cat has diabetes, their body is unable to produce or use insulin properly.
