Felis, the evil cat, stages a protest against being stuck in a tree.
From what I've been told, running up a tree is something cats are hardwired to do, but running down a tree has be learned at the University of Mom. Provided mom knows how to go down a tree herself. The counter-intuitive trick is going head first, supposedly. Kittens are often taken away from their mother slightly too early, so there's an epidemic of tree-related ignorance in the feline community.
Felis' mom did not know, it seems. And no fire department is ever going to show up around here. But Felis got down on her own after a while.
