Sleeping in Sinks & Basins

Comfort & cool-seeking

What it means: Comfort & cool-seeking

The curious feline habit of curling up in a bathroom or kitchen sink combines a love of snug, enclosing spaces with a preference for cool, smooth surfaces.

Few cat quirks are as photogenic — or as baffling — as the sink sleeper. There is something irresistibly comic about a cat folded neatly into a porcelain basin, and the behaviour is common enough to have its own genre of internet photographs. Behind it lie several very sensible feline instincts.

First, cats love spaces that hug them. A sink's curved sides press gently against the body from several directions at once, which taps into the same security-seeking instinct that draws cats to boxes, bowls and laundry baskets. That contact is reassuring, mimicking the safety of a snug den where a cat can rest without feeling exposed.

Temperature matters too. Smooth ceramic and metal stay cool to the touch, so on a warm day a sink is a natural place to shed a little heat. A basin near a window may also offer a sunbeam, a dripping tap to bat at, or simply a good vantage point over the room. Add the fact that bathrooms carry a strong concentration of their favourite person's scent, and the sink becomes a cool, cosy, familiar-smelling nook that is hard for a cat to resist.

Seen in cats of every breed, though heat-sensitive and thick-coated cats may seek out cool basins more in warm weather. Curious, quirky individuals who enjoy unusual resting spots are the most enthusiastic sink-dwellers.

When to worry: Almost never a concern — it is a harmless quirk. Occasionally a cat that suddenly seeks out cool surfaces far more than usual may be trying to cool down because it is overheated or unwell, so consider the wider picture if the behaviour appears abruptly alongside other changes.
