He hasn't got a litter tray as such. As a house bun I left him to go in his one place in his cage so that he didn't spray in random places and now I don't want to interfere with his placings. He has his corner in the cage so I can put mega zorb there and then put a mixture of hay and wood shavings to create a soft bottom. I'll still use newspaper as it adds that bit of protection from bacteria etc
Putting a litter tray in the corner wont upset his habits
