My friend has adopted a kitten. She's had him for almost two weeks, he was 12 weeks old when she picked him up, and he will NOT use the litter tray. He is pooing on the beds, on the carpet, and on the kitchen floor - lots of different places. She rang me in desperation; I suggested:
Using different kinds of cat litter
Putting bowls of food on the bed/places he poos
Picking up poo and putting it in the litter tray so it 'smells' like the toilet
Nothing has worked, she is cleaning up poo daily - and hasn't found any wee yet, so god only knows where he's doing that. She can't smell it.
She has two other adult cats, the male has accepted the kitten ok, the female will sniff him but then hisses (but there hasn't been any fighting).
Ideas please!
