A parents house with their wonderful 14 week old kitten , was using litter tray really well. previous old cat before it died pooed a bit round the house mum cleaned with bleach ( hard floor ) carpet shampoo ( carpets). Kitten has started pooing round the house as well as in tray despite having access to her tray ( all being it in another room). The hard floors we have got a anti fouling spray . Kitten has had lots of new paymates ( my dd's) and has started playing outside . cat experts what should we do ? she is a well loved adorable kitten, we had changed her cat litter , she uses it fine so don't think it is that. But having her pooing round the house is rather taxing......
