Maybe we should get some Charr-nip and watch him go nuts? Or maybe torment him with some bizarre objects and dangle them in front of him?
And you know if we keep Charr in our company, he'll be bugging us with insane questions like 'how many calories are in a mouse?' or 'what size litter box should he use?' And can you imagine the size of the hair-ball we'd get from that overgrown kitty?
Kinda makes me want to do some research though. A good book for this occasion might be, "One Hundred and One Uses for a Dead Charr."
