Thanks guys, Each hutch has a tray in it, as it is easier when cleaning the hutch. The two girls are the cleanest and do most of their toliet it. Twinkle is quite clean to but Cadbury just drops where he is standing.

It's when they come out of their hutches in the spare room that the problem starts. I have put trays down but still they prefer to do it on the floor.

What I shall do is try again by putting trays in both rooms when they come out of the hutch and I will let you know how it goes, it would be so much better for them if they done it in trays as I could leave them to roam about on their own a bit more.
