Hi Everyone
Thanks for all the replies and suggestions.
They actually share a tray, should they have one each??
No I've not changed cleaners recently.
The tray sits on an old piece of clean carpet, which she started doing her business on, so today I've taken that piece of carpet away, washed out and changed the cat litter and sat it down on some backing paper that's used for carpets, so we'll see how she gets on with that.
Fingers crossed!
Sally
