Poor Buster

My poor 3 legged cat is having spring fever in the worse way. Due to his condition I can't, as a good pet owner, allow him to go out side. Before his leg removal he was an avid outdoors cat. He would spend the whole day outside hunting and what ever else cats do. Now he is reduced to screen door hunting. Which is he lays down in front of the screen door and watches the birds. Occasionally he will pounce and startle everyone. This is just not enough for poor Buster but that is all he gets. I think I will go stir up some cat nip! :)
