Have you ever caught your cat in the sink and wondered what in the world they are doing there? If so, you’re not alone! Cats often curl up in the sink. Although they look very cozy and content in there, it’s hard to believe they are actually comfortable in a cold, hard sink. Let’s explore why some cats are obsessed with sinks.
It's common for cats to enjoy lying, sleeping, and hiding in sinks.
Cats might like the shape of the sink, its coolness, the fact that the sink is in a quiet room, or the proximity to running water from the faucet.
If you prefer to keep your cat out of the sink, close the bathroom door, offer your cat a sink-shaped bed, and praise them or give them treats when they sleep elsewhere.
1. Cooling Off
The cold ceramic or porcelain of a sink offers your cat some comfort as it allows them to cool down. If the weather is warm or you have the heating on in your house, the temperature might be too hot for your cat. Cats are covered in a thick layer of fur after all. They will often seek somewhere they can lie down and cool off. The sink is perfect for this as the material is cool to the touch so will allow the heat from your cat to transfer to it.
2. Perfect Shape
Your sink is usually the perfect shape for your cat to curl up in and fit snuggly. If you think about it, sinks are a pretty similar shape to cat beds. Sinks and cat beds also share a few other attractive characteristics for cats. Cats like to feel secure when they lie down or sleep. The sink contains them well, offering a nice, rounded shape that they can lie in comfortably.
3. Water on Tap
Another attraction for your cat is the proximity to the faucet. Cats just love to drink from running water. Most owners are aware of cats’ fascination with running water. We think this is because it’s easier to spot than still water, so they are attracted to it. This is also why you might catch your cat tapping the top of the liquid in a cup or a glass of water as they want to confirm if there is liquid in there or not.
The tinkling sound of the running water also attracts cats. Though domestic cats are no longer wild animals, they might find running water appealing as evolution has taught them that it is considered safer and cleaner than still water.
Lots of cats seem to prefer the taste of running water. Water in their bowl might taste unattractive to a cat, especially if it has residue from dropped food or if it hasn’t been washed properly. Even if you have washed the bowl really well, your cat might not like the scent of the cleaning products you used. It is best to regularly clean your cat’s bowl with an unscented cleaning product.
4. Vantage Point
The sink offers a great lookout post position for your cat. They can look out over the top of the sink while staying relatively well hidden. Cats like to keep a close eye on the activity in their environment as they are always on the lookout for threats. This is an instinct as cats can be predators or prey in the wild—they both hunt and are hunted.
5. Quiet Time
Cats often crave a quiet space to call their sanctuary. Your bathroom will usually be a quieter place for them to hide in as it is away from the usual hustle and bustle of the house. Your bathroom will usually only be occupied by one person at a time, compared to somewhere like the lounge or the kitchen which will often be busy with people and never quiet or empty.
Some clever cats realize that getting in the sink not only brings them physically closer to us but also that they will get lots of attention. If you are about to wash your hands or brush your teeth and you find your cat there, you will more than likely talk to them and pet them, even if you are doing this as you move them out of the way.
Your cat will begin to associate this with a positive experience and gravitate toward the sink for they some quality time and positive interactions with you, their favorite human!
How Do I Stop My Cat From Sleeping in the Sink?
If cat sink slumbering is not for you, there are a few things you can do to persuade your cat to pick a different spot. The first thing would be to keep the bathroom door closed to prevent your cat from sneaking in and curling up. If you do this, ensure you have other places around the house that they can go to as they might be very upset if their special place is suddenly out of bounds.
You can buy cat beds that mimic the shape of your sink which some cats might like as an alternative. Be sure to place them in a quiet room away from the usual foot traffic in the house. If you think it’s the dripping tap and running water element your cat is attracted to, you can buy water bowls that have a mini water fountain in it so it mimics a little stream or river.
You can also try reinforcing positive behavior, so if your cat decides to curl up somewhere other than the sink, be sure to pet them and make a fuss of them and give them treats. If they do keep going to the sink, calmly remove them and place them gently down somewhere else without giving any attention or fuss. It’s best not to scold your cat for going in the sink as this may frighten them.
Should I Be Worried if My Cat Hangs Out in the Sink?
Usually, if your cat is snoozing in the sink, this is just an adorable (if bizarre) habit they have picked up. However, there are a few reasons they might be going near the sink that could mean something is up. If your cat is hanging around the sink because they are constantly thirsty this could be a sign of something like kidney disease or diabetes.
If you notice your cat is extra thirsty and possibly using their litter box more too, it’s best to get an appointment with your veterinarian. Especially if this has come on as a sudden change. Your cat might have an underlying health problem that needs addressing.
Another issue some owners are concerned about is hygiene. If your cat is padding about your bathroom frequently throughout the day, at some point you know they will have just been in their litter tray.
If they are then walking around your sink where you wash your face and near to your toothbrushes, some people might think this is unhygienic and feel uncomfortable. This does depend on personal preferences.
There are many reasons you might find your cat in the sink. Most of these are behavioral explanations, however, there are a few reasons that might mean your cat is sick and needs some help from your vet. Once you have ruled out any medical issues you can let your cat lounge about to their heart’s content, as long as you are OK with it too!
