Hello! 2 8-week old kittens came to live with us on Sunday. Breeder assured me they were confident using litter tray. They're not; they're not interested in it, and are peeing behind an armchair in front room (keeping them in one room for now so as not to overwhelm them). I've put the tray there so that it's quiet and private, and there's another tray the other side of the room. It's made no difference. The internet tells me to pick them up and place them in tray, especially after eating. But they're so anxious and afraid of me currently that this just feels unkind, and certainly hasn't had any impact on their toileting. Is there anything else I could or should do?
