Some also note that the security of a box could mimic the snuggly warmth a kitten feels while cuddling their mother and littermates. as a result it is possible that while box sitting, a cat's body releases endorphins that cause pleasure and reduce stress.

Cardboard boxes are the most popular and ready available types of boxes that cats like. Cardboard might effectively retain the cat's body heat, creating a cozy environment.

Cat trees with high-up boxes and elevated hidey holes are felines favorites, while some cats refer hideaways closer to the ground. Experiment to see what your cat prefers.
