What am I?

This is a riddle
Wait and see
What you are looking for
Iives in a tree
It’s big and brown
And furry as well 
And has claws
To stop it falling off the end
It is slow to move 
And likes hanging around 
And this is usually upside down 
Its long claws makes it difficult to walk on land
But it’s a good swimmer that enjoy eating leaves for dinner 
What am I?
