Adopted a two year old male cat from Cat's Protection two weeks ago, he was a stray before we took him in. Settled in well, although a bit jittery. He's been outside every day the past week and comes home after an hour or two when hungry. Uses litter tray for wees but the past two days running he's pooed in the corner of my kitchen when he's been unattended. We use the same kind of litter as CP, his litter tray hasn't moved and he was using it properly beforehand. It started when I went back to work and he was alone during the day but I obviously can't stay at home with him and then he did it last night while I was sleeping. How can I stop it? I wouldn't be too irritated but I'm pregnant and worried about toxoplasmosis.
