Cats are headstrong, laser-focused creatures. If they set their minds on something, best believe they are going to do it. Let’s take napping in sinks, for example: if you don’t know the right techniques, it won’t be easy to persuade your kitty to leave the fixture alone. But wait—why do cats like to sleep in sinks, exactly? Don’t they have a strong antipathy towards water?

Well, it’s not that simple, and if you are a bit worried about your furry bud’s love for sinks, this guide is for you! Join us, and let us solve this mystery. First, we will go over the eight most likely reasons for this behavior. After that, we will talk about the best solutions to this peculiar habit. Here we go!

The 8 Reasons Why Cats Like to Sleep in Sinks

1. They Crave Peace and Quiet

Are you the proud owner of an active, energetic, and ready-to-rumble cat? That’s great news, but it doesn’t necessarily mean peace is not important for the pet. Since the bathroom is vacant for most of the day, cats like how quiet it is in there. That’s right: it could be that the sink is not necessarily what the cat is drawn toward. If you have little kids in the house who make lots of noise, this might be what is causing this behavior.

Other pets (like fellow cats or dogs), loud TV, and noisy appliances are even more reasons for a cat to seek solitude in the bathroom. In this case, the sink will just be a “bonus feature”, nothing more. So, before you start physically removing the domesticated animal every time you catch it in the restroom, try to lower the noise levels. That might just fix everything, especially if noise or activity in the home is contributing to the behavior.


2. The Sink’s Shape Is Comfortable

In many ways, the sink’s curved shape can provide a comfortable resting spot for a cat. So, for a cat that’s much smaller than a human, the sink is a perfectly shaped tub where it can take a nap and relax. Most sinks in the States are made of ceramics, cast iron, and composites, and stay cool for long periods. Imagine how great it feels to dip into a cold sink after spending most of the day under the sun!

As for the cold days, while sinks do take some time to heat up, once they do, these fixtures turn into the ideal resting grounds. Cats are always looking for ways to make their lives more comfortable. Plus, they need to feel secure, especially while they are resting and letting their guard down. That is another common reason. Let’s talk about that next.

3. Cats Appreciate Elevated Surfaces

Cats perceive their surroundings a bit differently than we do. To a cat, a sink is not just that: it’s a vantage point. Like most feline creatures, kitties like to climb as high as they can for that “bird’s eye view”. First, it may help them feel more secure and provide a better view of their surroundings. Some cats prefer elevated resting areas because they allow them to monitor their environment more easily. 


4. The Cat Craves Your Love

Have you been paying less attention to your cat lately than it deserves? Sometimes, we forget how important it is for our pets to feel connected with their owners. Therefore, sleeping in the sink might be the cat’s way of trying to get on your radar. A little bit of love and care—that’s all kitties need! So, try to give it a bit more “you time” for the next week or two and monitor its behavior.

And don’t worry: this doesn’t mean you’ll have to put a stop to everything else in your life. On average, cats require less than an hour of playtime a day to feel loved. Ideally, you should break that into four 10-minute sessions, as cats only stay active for short periods. If your cat is seeking additional attention, you may notice changes in its behavior once its social needs are being met.

5. The Bathroom Is a Perfect Playground

Cats like to follow us into the bathroom—that’s a known fact. Again, while it might feel a bit like a violation of privacy, this is often a sign that your cat is interested in your activities or enjoys being near you.

More importantly, while you’re busy with your morning ritual, the cat will be quick to get a “read” on the bathroom. The towels, robes, toilet paper, and rugs on the floor are fun to play with for a cat, along with the bathtub and the sink. Thus, what starts as a genuine desire to spend more time with you might slowly turn into the cat’s developing a preference for spending time in the bathroom, including the sink.


6. The Pet Likes to Be Near Water

Not all cats like to drink water from bowls. Instead, they prefer to get their moisture levels up by drinking the water running down from a faucet. It’s always cool and fresh, just the way cats (and humans) like it. Being near a water source is another common reason why cats tend to curl up in sinks and stay there for hours.

Besides, if you’re a long-time cat owner, we bet you’ve seen how fascinated they get around water streams. The way the water flows from a faucet/tap and the sounds it makes play tricks on most pets. So, while most domesticated felines hate being bathed, they don’t at all mind playing with water.


7. This Might Be Caused by a Medical Condition

Sadly, not all cats are drawn to sinks simply because they feel good to sleep in. Sleeping in a sink is usually normal feline behavior. However, if your cat has suddenly developed a strong interest in sinks or faucets and is also showing other signs of illness, it may be worth consulting your veterinarian. The most common causes of constant trips to the bathroom looking for water to drink are various kidney diseases and diabetes. As mentioned, cats like to drink from faucets. That’s why they often pick the sink.

When a cat is diabetic or has faulty kidneys, it tends to urinate and drink more. Look for additional signs such as increased thirst, increased urination, weight loss, changes in appetite, or decreased energy levels. If you notice any of these symptoms, schedule a veterinary examination.

Also, take a long and hard look at your pet: does it look like the kitty has lost some weight? If so, get in contact with a vet ASAP. Or, better yet, visit a veterinarian that you know and trust and ask them to check the cat thoroughly. The sooner an underlying medical condition is diagnosed and treated, the better the outcome may be.

8. Just Because!

Cats are spontaneous, adventurous fur balls. So, if you find it crawled up in the sink, that might be simply because it’s feeling like it. Sometimes, cats like to “investigate the premise”, and once they find a spot that’s equally safe, comfortable, and away from prying eyes, they stick to it. Or, at the very least, they give it a try.

In other cases, it is a combination of some of the reasons we mentioned earlier. The takeaway here is that as long as the feline is not drawn to the sink for medical reasons, you shouldn’t worry about it. This is especially true if you just moved into a new house or apartment and your wild-at-heart pet is eager to check out every spot and become familiar with its surroundings.

Why Is Playing Important for Cats?

Veterinarians believe that regular constructive playtime for a cat can make it happier, improve the pet’s health, and help reduce stress. Much like children, cats are socially flexible creatures that can build strong relationships with their family members, be it other cats or human moms/dads. Besides, playing will help you keep the cat in shape.

Unfortunately, obesity among domestic cats is a common and serious health concern. It not only makes them slower and less active but also affects the quality of their lives and often leads to severe health issues. Fortunately, you can fight that and make the kitty more social and adaptive by introducing a little more playtime into your daily routine.

  • Stopping Your Cat From Sleeping in the Sink: A Quick Guide

    Alright, now that we’ve found out why cats use sinks as improvised beds, it’s time to learn how to talk them out of it. Here’s what you can do to solve the problem while keeping the cat happy and maintaining the same level of love and trust between the two of you:

    • Buy a similarly-shaped cat bed. So, your furry friend likes the smoothness of the bowl and how comfortable it is? Well, why not try and introduce it to a comfy raised bed that looks and feels exactly like it? In most cases, that will be enough to make the fur ball abandon the sink—for good. But don’t be harsh about it! Gently offer an alternative resting spot instead of pushing it.
    • Make sure the door is closed. Cats are curious by nature and will always want to check what’s behind a half-opened door. One way to counter this is to keep the door closed at all times, no matter if you’re home or away. While this will take training and positive reinforcement, give it some time, and the kitty will lose interest in the bathroom door.
    • Stop petting the cat in the sink. Nothing feels as rewarding as petting the cat early in the morning. On the downside, if you do it frequently while the kitty is cozied up in the bowl, that might give it the wrong impression. That’s right: the cat will think that it will only get love from you while it’s in the sink!
    • Use scents that cats don’t like. There are quite a few odors that draw cats away yet pose zero threat to their health. So, if you want the little troublemaker out of the sink, do consider putting some of these to good use. Pet-safe citrus-scented deterrents formulated specifically for cats may be helpful in some cases. Be patient, and the results will come!

    Conclusion

    If you are a veteran cat parent, you already know that they like to catch some Zs in the most unusual spots. And the sink is one of those places. A first-time cat owner, in contrast, might be caught off-guard when they see this. But don’t you worry: unless it’s caused by a medical condition, this behavior is totally okay.

    Now, there is more than one reason for fur balls in the bowl. And the best part is, there are some tried-and-true techniques for convincing the cat to let you use the sink to wash/brush your teeth. All you have to do is use the right approach, be patient, and show love and respect to your four-legged friend—that’s all there is to it!
