Our feral kitten won't use the litter box and only uses the carpet, we've seen her pee once outside on leaves but her time outside is limited due to a hostile feline neighbour. I recommended that we put carpet in the litter tray then gradually add cat litter until she's used to the idea. She was born on a farm and I've seen her sister (born on the same day) bury her mess so I know the kitten has seen it or even knows what to do. But has anyone tried my idea of using carpet then slowly putting dirt on it, how did it work out for you?
