How Much Water Does a Cat Need?

As cat owners, we all want our furry friends to be healthy and happy, but one area that often gets overlooked is hydration. Cats are notorious for not drinking enough water, which can lead to serious health problems, like kidney issues or urinary tract infections. 

So, how much water should your cat be drinking? Let’s break it down and explore some common mistakes we make when it comes to our cats’ hydration.

On average, a cat should drink between 50-70 ml of water per kilogram of body weight each day. For example, if your cat weighs 4 kg, they should be drinking 200-280 ml of water daily. This includes both the water they drink and the moisture they get from their food. Cats that eat dry food will need to drink more water compared to those who eat wet food, which is naturally higher in moisture content.

Dry food contains only about 10% moisture, while wet food can have up to 80% moisture, so your cat’s diet plays a significant role in determining how much extra water they need.

Common Mistakes Cat Owners Make

Relying Too Much on Dry Food

One of the most common mistakes is feeding cats exclusively dry food without compensating for the low moisture content. Cats evolved as desert animals, and their natural prey (like mice) consists of about 70-80% water. When cats eat only dry kibble, they often don’t drink enough to make up for the deficit.

If your cat is on a dry food diet, make sure they always have access to fresh water and consider incorporating wet food into their diet. In different locations, try a cat fountain or even add water to their food.

Not Monitoring Water Intake

It’s easy to overlook how much water your cat is drinking (or not drinking). Some cats may not like the taste of tap water, or they might be picky about the cleanliness of their bowl. 

Keeping an eye on their water intake can help you catch any early signs of dehydration. If you notice your cat is drinking less than usual, it might be time to switch up their water source or check for underlying health issues.

Using One Water Bowl for Multiple Cats

If you have more than one cat, you might assume that one water bowl is enough for everyone. 

However, some cats are territorial and may not want to share, leading to one cat drinking less than they should. It’s best to provide multiple water sources throughout your home to ensure all your cats are getting enough water.

Not Using the Right Type of Water Bowl

Cats can be finicky about the type of bowl they drink from. Some prefer wide, shallow dishes that don't press against their sensitive whiskers, while others might prefer drinking from a flowing water source like a pet fountain. 

If your cat is ignoring their water bowl, experiment with different styles to see what they prefer.

Assuming Cats Will Drink When They Need To

Unlike dogs, cats aren’t as naturally inclined to drink water. They tend to be poor drinkers, and by the time they feel thirsty, they may already be on the verge of dehydration. 

Encourage water intake by placing water bowls in different locations, trying a cat fountain, or even adding water to their food.

Signs Your Cat May Be Dehydrated

It’s important to watch for signs of dehydration, especially if you suspect your cat isn’t drinking enough. Common symptoms include:

Lethargy, Sunken eyes, Dry gums, Poor skin elasticity (if you gently pinch their skin, it doesn’t bounce back quickly)

If you’re concerned, always consult your vet. Dehydration can lead to more serious health problems, so it’s essential to address it promptly.

How to Encourage Your Cat to Drink More Water

Add water to wet food: If your cat eats wet food, add a bit more water to increase their intake.

Use a pet fountain: Many cats love drinking from moving water, and a fountain can make hydration more fun for them.

Place bowls in multiple locations: Cats can be creatures of habit, so having bowls in different areas of your home might encourage them to drink more.

Offer different types of water: Some cats prefer filtered water over tap water or enjoy a cold, refreshing drink from the fridge. Experiment to see what your cat likes best.

Keeping your cat properly hydrated is one of the easiest ways to support their overall health. By understanding their water needs and avoiding common mistakes, you can ensure your feline friend stays healthy and happy for years to come. Remember, every cat is different, so it’s important to pay attention to their unique preferences and needs.

If you’re ever unsure about how much water your cat is drinking, don’t hesitate to consult your veterinarian. After all, a well-hydrated cat is a happy cat!
