Our cat has been really good at using her litter tray ever since we had her, but normally prefers to go outside. Since all the fireworks she's lately started to use the litter tray again but for some reason every morning we find pee in the bath. DP swears its not him (!) and I don't think I've been sleep-peeing so must be the cat. Anyone had any experience of this? How can we get her to stop? DP said we could just keep the bathroom door shut but I'm scared she'll find somewhere else to do it and I don't fancy finding the house smelling of cat pee and not knowing where its coming from!!
