We are three weeks in our new home, and cats just getting confident outside for short trips when a dog not on a lead got into our garden and one ran up a tree to escape. She's now up a huge willow tree (about 3 stories high) and I've no idea how to get her down. The branch she's on is pretty vertical - climbs me for her on the way up with claws but getting down seems to be a very different thing. How long to leave her to it? And if she is stuck who or what can get her down?? Any ideas or experience gratefully received.
