Please help there is a tiny kitten stuck in a tree
I don't know quite how to get him down, but one thing to think of - have you ever seen a cat skeleton in a tree? :) Of course it's still upsetting to see a poor little animal in distress. I can only think of using a ladder, but you probably already had that thought.
Check this link. It does seem concerned if it is a kitten. It suggests calling a local animal rescue or your vet.
Glad to hear the kitten got down!
