Tucker and I have a game we play now -- and, it involves me "fetching," of
course. Tucker will sit in the top bed of the tallest cat tree and wait for
me to throw little balls of paper up into his "nest."  Then he'll bat them
down and all over the place for me to retrieve ("here, hoomin, Fetch, fetch,
I say") and toss them again.  A lot of times the paper balls will fall down
the access hole to his nest and he'll shake the cat tree hauling down after
them.  It's a great way to wear both of us out!
