We have 2 18 month old cats. Since they started going outside they haven't used the litter tray, although we have kept it.
Problem is the ground outside is frozen solid and one of them absolutely has to bury everything. So I think she's just not going.
Any suggestions? I've bought another litter tray, which she will sit in but not poo. Is there a more soil like brand of litter I could try? Or should I use hot water to thaw a patch outside? Kitty keeps going in and out and in and out and I see her trying to dig in the flowerbed but she can't.
