cats

Adult cats meow mainly to communicate with humans, not with other cats.

Cats bring prey home because home is their safe territory, and hunting instinct remains strong even when they are fed.

Cat tongues are covered in tiny hollow spines that act like a comb and wick saliva deep into fur.

Boxes give cats a safe, warm hiding spot to watch from, which lowers stress.

Cats have a reflective layer behind the retina called the tapetum lucidum, which bounces light back through the eye.

Cats hiss as a defensive warning when they feel threatened, telling the other animal or person to back off.
