Cats just can't help themselves; they're super curious and love a good adventure, which often means climbing up high to see what's up or chasing after birds. They also climb to get away from dogs, other cats, or anything else that freaks them out on the ground.But, getting up there is one thinggetting back down is a whole other ball game. Their claws are great for climbing up but not so great for coming down, not like. squirrels who can go any way they please. Cats usually have to back their way down trees because they can't go down headfirst, except for this cool cat called the margay in the rainforests from Mexico to South America, which can do it.
