Providing your cat plenty of drinking water can help prevent him from developing painful kidney stones.

Sometimes it can be hard to tell when your little furbaby isn't feeling well. Cats are such resilient pets that they don't exhibit many tell-tale signs when experiencing internal pain. Because of this, it is important to prevent your kitty from the potential dangers and pain of kidney stones.


Provide your cat with plenty of drinking water. According to the Journal of Veterinary Internal Medicine, he should be drinking about 30 ml of water per pound of body weight each day in order to maintain good hydration. Proper hydration is one of the most important preventatives against the formation of kidney stones for your cat.

Feed your cat a healthy diet. It is important to know what to look for in a food for your precious pet. For instance, cat foods labeled "for urinary tract health" can be misleading because this type of food is designed to make a cat's urine more acidic, and this will actually increase the formation of kidney stones in cats that are at high risk of experiencing them.

Watch your kitty when he goes to the bathroom and check his urine for signs of crystals or stones. If you notice he is trying to urinate but can't go, then his kidney stones may be blocking his urinary tract and this can be serious. You should take him to the veterinarian as soon as possible.

Follow the advice of your veterinarian for any other preventative measures or treatments for the kidney stones if your cat already has them. In most cases, you will want to ensure your kitty gets X-rays on a monthly basis until it is determined that his kidneys are free of stones.

Items you will need

  • Water
  • Healthy cat food


  • Adding a 1/4 teaspoon of salt to your cat's water (with vet approval) will help increase his water consumption because the salt will make him a little thirstier.
  • Use a water bowl that is large enough so his whiskers don't touch the sides of the bowl. Small bowls can sometimes make a cat less comfortable to drink.
  • Make ice cubes out of the water in cans of tuna fish and place them in your cat's water to dissolve. The aroma may encourage him to drink more water.


  • Do not give your cat calcium supplements.
  • Do not try to treat your cat without the guidance of a veterinarian.
