In the middle of a sound sleep, I’m often rousted awake by the noise of Casey’s metal identification tags clanging against the stainless steel water bowl in my bedroom. Instead of being irritated, I smile knowing that my orange tabby is staying hydrated by lapping up water.
Unlike dogs, most cats are not big gulpers or slurpers at the water bowl. And I’ve yet to see any feline expert consistently train a cat to drink water on cue. But, like dogs, cats need ample daily supplies of water to keep their coats shiny and their skin and organs well hydrated. In fact, a cat’s body is made up of about 70 percent water.
For insights into H20 for cats, we turned to a champion of all cats: Dr. Ernie Ward, America’s Pet Advocate and a member of the American Association of Feline Practitioners’ cat-friendly practice advisory council.
Catster: How much water should an adult cat drink each day to stay hydrated?
Ward: Because cats evolved in the desert plains of Mesopotamia, they require a little less than an ounce of water per pound of body weight each day. An average 10-pound domestic shorthair indoor cat will typically need to drink 7 to 10 ounces of water per day.
Should we be concerned if our cats don’t always drink this recommended daily amount of water? Or if they seem to be drinking excessively?
The biggest problem of water consumption in pets involves excessive drinking. If your cat is suddenly lapping at the water dish frequently, drinking from unusual sources (like the toilet bowl), or is urinating more than normal, have him examined by your veterinarian immediately. Diseases that cause increased thirst include kidney and liver disease, diabetes, hormonal imbalances, and cancer. One in three cats will experience kidney disease.
If a specific cat doesn’t drink much water, is there a Plan B to make sure he stays hydrated?
Feeding a canned diet is an excellent way to provide water for your cat. Canned food is between 70 percent to 80 percent water. Many cat owners who feed a moist or wet food rarely observe their cats drinking from a bowl or a water fountain, and they shouldn’t be alarmed. This is because their cats are consuming much of their daily water requirements from their diet.
Any ideas to make water sources more interesting or inviting for our cats, especially if their primary food source is kibble and not canned food?
Many cats seem to prefer fresh, running water from a pet drinking fountain or circulating water bowl. While it’s unclear why many felines prefer bubbly water, one theory is that running water signals safety. Cats may have evolved with a preference for running water because still, stagnant water can harbor infectious parasites, fungi, and bacteria.
Any tips on the best type of water bowl to provide for our cats?
Most veterinarians recommend using stainless steel or ceramic food and water bowls for cats instead of those made of plastic. Some cats are sensitive to plastic and can develop skin allergies over time. Other concerns are that volatile compounds contained within the plastic may leech into food or water, causing potential harm. If you use plastic bowls, make sure they are BPA free.
