Toffee sure is a character.
It is good to know that lots of hamsters do this. We have read lots of things that say that hamsters like to do their toilet in the furtherest corner from their bed but before we put in the jam jar Toffee just weeed in the corner near his bed. Even with some coaching he still went there so in the end we left the jam jar there where ever he was happy with it being and he now just goes in there nowhere else. Whatever makes him happy.
