IS it blood or just off colour wee? I am concerned as this is the front of the tray and they don't normally wee there and its all over the carpet as well and they have never weed on the carpet.
I have checked them over and there are no obviously signs of blood, will thoroughly check when O/H comes home as Lolly has just scratched me really badly and I couldn't hold her to check her underneath.
What do you all think?
