1. Cats can see in the dark. Their eyes are adapted to low light conditions, and they can see up to six times better than humans in the dark. This is because their retinas have a higher concentration of rods, which are cells that are sensitive to low light.
2. Cats have retractable claws. This means they can extend their claws when they need to, such as when they are hunting or defending themselves, but they can also retract them when they don't need them. This helps to keep their claws sharp and prevents them from getting damaged.
