Why do cats follow you into the bathroom?

If you spend enough time browsing the internet, you’ll inevitably come across pictures or stories of cats lurking by bathtubs while their owners shower, fascinated by the sight of humans deliberately getting wet. For example, on the subreddit r/lifeguardkitties, cats can be seen hanging around tubs or peeking out from behind shower curtains. (‘Cats concerned for their bathing owners,’ the subreddit description humorously claims.) This behavior is noticeably distinct from cats simply enjoying the coolness of a bathroom sink. It almost seems like a form of feline voyeurism. So why do they do it? Are they concerned for their human’s well-being? Or, as is typical for cats, is the answer more enigmatic and mysterious?

Why do cats trail you to the bathroom?

Although most cat breeds naturally dislike getting wet, as it results in an uncomfortable, soggy coat, they often don't mind being near water when their owner is showering or bathing.

Though no concrete explanation exists, a few common theories stand out. One popular belief is that cats possess an inherent fascination with water. When they see faucets running, they’re often captivated by the movement of the liquid or its shimmering reflection. A shower, akin to a large running faucet, draws their attention in the same way, with the added bonus of involving a human.

However, this doesn’t account for why cats are so intrigued by watching humans relax in a bath with no water flowing. It’s possible they’re curious because their human is occupying a space that might feel like their own. Cats tend to enjoy the privacy and cool surface of empty tubs. A human being there—especially with water involved—could cause a cat to be fascinated by the situation, or perhaps they’re simply waiting for their turn to use the tub once you're finished.

This becomes even more plausible if your cat shows signs of unease while you bathe, such as meowing or pawing at the curtain. These behaviors may indicate your cat is ‘guarding,’ a protective instinct where animals seem to watch over their owners. To a cat, running water, flushing toilets, and bathroom noises signal potential threats.

Another well-known theory suggests that cats are drawn to the moisture in showers or baths, finding comfort in the warm air that surrounds the tub. This could be part of a broader affinity for bathrooms, which also contain sinks, cozy bath mats for lounging, and potentially even their litter box—all elements that create a secure environment for them.

It’s important to note that although cats generally avoid getting wet, not all breeds follow this pattern. For instance, Maine coons and Japanese bobtails are more water-friendly and may even explore a damp tub after you’ve finished your bath.

Why Cats Are Fascinated by Watching You Pee

Cats’ curiosity doesn’t stop at bathing—they also seem captivated by their owners’ bathroom routines. Some owners report that their cats enjoy watching or even engaging with them while they’re on the toilet.

Cats might see this as an opportunity for undivided attention, approaching you just like they would when you sit down to watch TV or go to bed. The fact that you’re in a more vulnerable position doesn’t faze them at all.

When Things Start to Feel Awkward

If having a cat observe you while you bathe makes you uncomfortable, you can simply close the door. Alternatively, try offering a distraction. Most cats, when faced with the choice between watching you wash your hair or having dinner, will likely choose the meal.

If you're still wondering why your cat insists on joining you in the bathroom, it might be time to reflect on your own actions. If you regularly pet your cat when it’s on the sink or floor, you're reinforcing that behavior. Once a cat learns that being in the bathroom brings positive attention, they’ll likely continue to turn bathroom time into a shared experience.
