There are several reasons why cats climb trees, mostly to do with defensive purposes. Cats, as predators(捕食者)，like to understand their environment well. Cats climb trees to get a better view or their surroundings, to help them see any potential dangers or potential prey（被掠食者）.

While cats are predators, they can also be easily attacked by larger animals. A tree often provides a safe hiding place. In the wild, cats climb up trees to give them a resting place that is out of predators’ range. It also helps disguise their presence, which can prevent any prey from noticing that there is a cat nearby.

Sometimes some cats may climb trees for fun, or possibly to work on improving their climbing abilities. Kittens frequently test out their claw skills by trying to climb up everything, from bookcases to trees to a person’s leg. Climbing practice is good for cats; it can improve their strength and flexibility and teach them an important defensive skill. To prevent them from practicing indoor climbing of your furniture, however, owners may wish to buy a carpeted cat tree for climbing.

If a cat has gotten up a tree and cannot get down, the owner may wonder why its remarkable climbing abilities only work in one direction. A cat’s claws curve（弯曲）inward, allowing it to take hold of surfaces while going up head first. Unfortunately, this useful climbing curve does nothing to help the animal get back down again. Eventually, most trapped kittens will either jump out of the tree or realize that they can get down by going tail first. Either way, a cat up a tree is usually nothing to panic about unless it is injured; they are intelligent animals and will find out how to get down sooner or later.
