Well, now we're the weirdos who not only have a cat tree, but keep their toilet paper in tupperware. It was a very cheap alternative to the decorative TP covers I was able to find online (apparently these went out of style a while back) and they are totally Bear-proof. He has battled these boxes hardcore and never won.
So yeah, life with a kitten who has entered the "terrible twos" of cathood is interesting. His play aggression is more prominent and he's more destructive... both things we're trying to work on. My hope is that in a year or so he mellows out a bit, since he is so young.
