What is it about cats in sinks? Perhaps it's the size, the shape, the way they produce fresh water, or maybe it's just because it is so fun for a cat to be right in the way!
If you can't get enough of Maine Coons, you'll love our fun, free Daily Digest!

Whatever the reason, it sure is cute when a kitty decides to take a nap right in the sink.
We have collected quite a few sink photos over time, so here they are all in one place - Enjoy! (Each one is marked with the Photo Album he or she also appears in).
Maine Coons do indeed like water!
A bathroom sink may look like a ridiculous place to sleep, but from a cat's point of view, it has quite a bit going for it.
The curved basin fits naturally around a curled-up body, creating a snug little resting spot with the sides surrounding them. [1] Catster notes that the shape and size of a sink can make it an appealing place for a cat to curl up.
Then there's the surface itself. Porcelain stays relatively cool, which can make a sink especially appealing when a cat wants to shed some body heat.
Cats don't rely heavily on sweating the way we do; choosing a cooler place to lie down is one of the behavioral ways they regulate their temperature. [1] [2]
And for some cats, the faucet adds another attraction. Cats can learn that fresh water appears there, and some become fascinated with dripping or running water. Cornell notes that running water can encourage some cats to drink more. [3]
So that strange little nap spot checks several feline boxes at once: snug, body-shaped, cool, and sometimes conveniently located next to the water supply.
Whatever the exact attraction for each cat, MCCN readers have been catching theirs curled up in sinks for years. Here are some favorites from the photo albums.
