Why Do Cats Cover Their Face When They Sleep?

Why do they cover their face?

The most straightforward reason is light sensitivity. Cats are crepuscular and their eyes are adapted for low-light hunting. Bright room light can be uncomfortable during deep sleep, and covering their face blocks it out. It also conserves body heat; the nose and ears lose heat quickly, and tucking the face into the paws or body creates a warmer microenvironment. There's also a protective element. The face contains the most important sensory organs (eyes, nose, whiskers), and covering them during sleep's most vulnerable moments is an instinctive safety measure.

Why do cats bury their poop?

In the wild, burying feces serves to hide a cat's presence from predators and from dominant cats whose territory they may be passing through. Leaving feces exposed is actually a territorial statement; dominant wildcats and large cats often leave their scat uncovered as a way of announcing their presence. Your domestic cat buries their poop because instinct tells them they're not the top predator in the environment, so concealing their scent is the safer strategy. This behavior is one of the things that makes litter boxes work so naturally for cats.

What if my cat doesn't bury their poop?

Some cats don't bury, and it can mean a few things. In a multi-cat household, the dominant cat may leave their waste uncovered as a territorial signal. Some cats skip burying if the litter box is dirty, too small, or has a litter texture they dislike. Occasionally, a medical issue (pain in the paws, arthritis making digging uncomfortable) is the cause. If your cat suddenly stops burying after previously doing so, it's worth investigating whether something in the litter box setup has changed or whether they're experiencing discomfort.
