Is there anything that does not need to remove cats from trees? Any cat can freely descend on its own.

Theoretically it can. But successfully, this does not happen to everyone, mostly only in those who grew up on the street, whom mothers in childhood taught to descend. Cat skeletons on trees - HAPPEN, although rarely, when the cat failed to fall on the underlying suck and died right there. How many fall to the ground, slumber and die in the basements, we will never know. So either teach your cat to climb before it gets stuck on a tree, or call an emergency call. Yes for money. Yes, they will go to this challenge only if they want and only when there is no need to save people. And at any time they will leave if their emergency help is needed by people. So don’t have to hysterize that "because of your cat people are dying". This does not really happen.
