We always have someone housesit when we go away. Our male Burmese gets too neurotic otherwise. He can't be left on his own for too long. Though it's a little trickier since our elderly female Burmese decided to start using the spare bedroom as her bathroom, meaning we had to get litter trays. Someone (we're not sure who) sometimes decides to poop outside the litter tray as well. THankfully the house sitter didn't say anything, so hopefully there weren't any accidents or she's too nice to say anything!
