My cat has tons of toys. I buy him crap all the time. His favorite toys are always trash, though. I bought this fancy version of those toy-on-string-on-stick toys where the toy can detach and be swapped out with some six other options. He barely likes it. Gift bow from a christmas present? HIS FAVORITE THING IN THE WORLD. He likes how it crunches when he chews on it. So I bought him one of those crinkly balls like in your first post. He doesn't care. Bought him a mouse that squeaks and lights up when moved. He doesn't care. But tissue paper from gift bags? Big, long strip of cellophane that wrapped around a lampshade I bought? Oh hell yeah.

God forbid he play with anything that doesn't make it look like there's trash strewn about my floor...
