What stops animals’ fur from getting too long in the wild?

Question

Obviously wild animals can’t get their fur trimmed every now and then so how does it stay at a relatively consistent length? Does animal fur start growing when animals are born and then just stop at one point?

Answer 1

The same thing that stops the hair on your legs and arms from growing too long but magically consistent in length if you don’t shave it. The hair follicle dies after a certain age and the hair sheds, then a new hair grows in it’s place. Animals with very long hair like sheep and certain dog and cat breeds don’t have naturally long hair, it’s a result of hundreds if not thousands of years of selective breeding.
