How to Get Your Cat to Drink More Water

| |

Hydration is important for your cat. Just like in humans, getting enough water is important for proper biological functions. Daily access to fresh, clean water is an essential part of maintaining the health of your cat.

Cats, especially ones on a mainly dry food diet, need access to fresh water. Dry food typically contains 6-10% water. Wet food, in contrast, contains about 75% water.

Keep Your Cat’s Water Dish Away from the Food Dish

Your cat seems to love to drink from the water faucet or even from your class but doesn’t ever seem to touch his or her water bowl in the kitchen. Have you ever wonder why? Chances are, it’s because you have the water bowl too close to your cat’s food.

As humans, we are used to settling down with a drink while we eat our meals. We automatically assume our cats want the same setup.

In fact, cats don’t like their water near their food source. Why? From an evolutionary standpoint, cats learned that prey can contaminate water, leading to disease.

So set your cat’s water dish away from where he or she eats.

Don’t Put Your Cat’s Water and Food Dish Near the Litter Box

The same logic applies when it comes to serving your cat food or water near the letterbox. Make sure the litter box is in a different room from where you offer food and drink.

If space is limited, then try to put the litter box into an enclosed area or set the food and water dishes as far as possible from the box. Place the water dish higher up on a table or a shelf to keep the water dish separate from the food and the litter box.

Keep that Water Fresh

Make sure you refresh the water bowl often. Don’t leave water out for days where it can become stale and contaminated with food and debris,

Offer Running Water

Cats love to drink from running water. I have one cat that loves to join me at the sink every morning so she can drink straight from the faucet.

Another cat loves to have the bathtub filled with a little bit of water so he can drink from there. To keep the cats happy, I ended up keeping a fresh bowl of water sitting in the shower stall to satisfy their thirst.

One option for offering a source of running water is a cat water fountain. Pet fountains provide a continuous circulation of water which appeals to the cat’s inherent desire to drinking from a source of running water.

How Much Water is Too Much for Cats?

Excessive drinking by cats is know as polydipsia and can indicate a health issue in your cat. A ten-pound (4 kg) cat should be drinking (or consuming with their food) about a cup of water a day.

If you notice your cat drinking or peeing more than normal, it’s best to have your pet examined by a veterinarian to make sure there isn’t a health issue.

How do Cats Drink Water?

Researchers in 2010 analyzed the mechanics of how cats drink liquids. Researchers from MIT, Virginia Tech, and Princeton discovered that the top of the cat’s tongue is the only surface that comes into contact with the liquid in recent high-speed images.

If you’ve ever watched dogs drink, you will notice they don’t drink like cats. The lapping process of the cat is more subtle and the cat will dip just the tip of its tongue into the liquid. A column of liquid forms between the traveling tongue and the liquid’s surface as it does so. The cat then shuts its mouth and pinches off the top of the column for a drink, keeping its chin dry.

When the cat’s tongue comes into contact with a liquid surface, some of the liquid adheres to it due to liquid adhesion, similar to how water adheres to a human palm when it comes into contact with a pool’s surface.

The cat’s tongue is drawn back up so quickly that inertia overcomes gravity for a fraction of a second, pulling the liquid down down into the cup. The cat then shuts its mouth before gravity overtakes inertia.

That same research found that domestic cats drink at a rate of four laps per second.
