Is my kitten drinking enough?

Cats have evolved from desert-dwelling animals and have a naturally low thirst drive. However, modern-day domesticated cats, including kittens, may face various urinary diseases and infections if they don’t get enough water. Here's how to ensure your kitten is drinking enough and staying healthy.

Why water intake is essential for kittens

Water helps maintain the function of your kitten’s vital organs. It keeps their digestion smooth and supports overall growth. Hydration is especially important for preventing common urinary issues. While cats are naturally less inclined to drink a lot, encouraging good water habits early on can significantly benefit your kitten's long-term health.

Signs your kitten may not be drinking enough

If your kitten seems lethargic, has dry gums, or produces very little urine, it might be a sign of dehydration. Additionally, their skin may lack elasticity, and their eyes might appear sunken. Always monitor these signs to ensure they are drinking enough water, especially during the early weeks of their life.

Tips for providing water for cats

Cats can be picky about their water sources. Many prefer cold, fresh water, but not straight from the fridge. Some enjoy drinking rainwater or from dripping taps. It's important to change their water at least twice a day to keep it clean and fresh. Always rinse their water bowl well, as cats are sensitive to the smell of soap or chemicals. Keep their water dish away from food bowls, as cats view food as a contaminant and prefer to drink from a separate area. Using a water fountain can also encourage them to drink more.

How much water does a kitten need?

The amount of water a kitten needs depends on their age, diet, and environment. A 1-week-old kitten typically gets hydration from their mother's milk, so they don’t need water yet. However, as they begin to wean, usually around 4-5 weeks, they will start drinking water alongside eating solid food. 

A general rule is that a kitten should drink 30-60ml of water per kilogram of body weight per day. This can vary depending on whether they are on a wet or dry food diet. Wet food provides some moisture, but it’s still essential to have fresh water available.

How can I get my kitten to drink more water?

1. Switch to wet food

One of the easiest ways to get your kitten more hydrated is to switch to wet food. Wet food contains a higher moisture content than dry food, helping maintain their hydration levels. You can also add a little water to their wet or dry food to increase moisture intake.

2. Provide bottled or filtered water  

Some kittens may not like the taste of tap water because of the chemicals used to purify it. If your kitten seems reluctant to drink, try offering bottled, filtered, or boiled water that’s been cooled down.

3. Invest in a cat water fountain  

Kittens often prefer to drink from moving water sources, such as dripping taps or rain puddles. A cat water fountain mimics these conditions, encouraging your kitten to drink more. The constant flow of water is more appealing and keeps the water fresh, which is crucial for a kitten’s hydration.

4. Use wide, shallow drinking bowls  

Cats can be sensitive to their whiskers touching the sides of their bowl while they drink. Using a wide, shallow bowl can help them feel more comfortable. To encourage your cat to drink regularly throughout the day, try placing several water dishes around your house.

Special considerations for younger kittens

Can a newborn kitten drink water?  

No, newborn kittens (up to 3-4 weeks old) should not drink water. They rely entirely on their mother’s milk or kitten formula for hydration.

Can 1-month-old kittens drink water?  

Yes, by 1 month, kittens should begin drinking water alongside their mother's milk or formula. Ensure water is always available and fresh.

What about a 5-week-old kitten?  

At 5 weeks, your kitten is likely transitioning to solid food and will need access to water. Encourage them to drink by offering water in an easily accessible bowl.

Feeding bottles for kittens

For very young kittens who are still nursing, feeding bottles can be used to provide kitten formula. Water is not appropriate for kittens under 3 weeks old, as they need the specific nutrients found in milk.

Can I give my kitten milk?

Never give kittens cow’s milk. The lactose in cow’s milk can cause digestive issues like diarrhoea. If you wish to give your kitten milk, always choose a specialised cat milk, which is lactose-free and available in most pet stores. This milk is formulated to be safe for your kitten and won’t upset their stomach.

Ensuring your kitten stays hydrated is crucial for their health and well-being. While they may not have a strong natural thirst drive, there are several ways to encourage your kitten to drink more water. Switching to wet food, providing filtered water, and using a water fountain can make a big difference. Always keep an eye on their behaviour and hydration levels, especially during their early weeks.
