I know this subject has been touched on but I'm at the end of my tether so thought I'd do an post for it. When I first got my cat she wee'd behind the TV. This was insecurity and soon sorted itself out (or so I thought). The cat uses her litter tray and doesn't wee anywhere other than the same spot behind the TV. Now the vet has said once a cat has been in an area they tend to return to that area and you need to get the urine out and the cat wee enzyme present in their wee out to make sure they can't find the spot and reoffend. I appreciate she regards this spot as her wee area but it's not!!! I've tried biological liquid, followed by surgical spirit but she is still reoffending on that area so it's not getting rid of whatever it she can smell to find the 'spot' again. HELP! Hints, tips, lotions and potions appreciated. I've got new carpet so don't want to have to replace it!
