A while ago Jack and Isobel started weeing on the floor near the tray, after a trip to the vet we changed the diet to wet food and Jack stopped. Isobel only wees on the floor once a day in the middle of the night when we are not looking but when we are around she uses the tray. She has non of the usual UTI symptoms, no smelly wee, no pain when weeing etc. I wonder if it is just that the floor smells (which it does) and she feels like she should wee there. We can't get the floor to smell good, we have tried allsorts of anitbacterial sprays/wipes, different scented floor cleaner but it still must smell really strong for Izzy cuz sometimes it smells a bit to us and we don't have cat noses.
