Its nothing major but SOMETIMES my kitten sophie goes to the toilet just outside her tray. She has a strange habbit of even when she goes inside she does not cover up as she tries to cover up outside the tray. So it smells
Main thing though is going outside.
Is there any way of getting her to stop going outside the tray? I mean we are talking inches here

Her mother, Asia is a lot better. She only goes outside if she does not get in all the way and it falls over the side

She does usually cover up though.
I was thinking maybe an enclosed one might solve it and force them to have to go inside. Good idea?
