When I went to see Peter (Oliver??) this morning, he wasn't in the trash can!!! He was hiding behind the toilet, but still, it was huge. I got him to come out on his own by offering him some food, which is also a big step for him.
His tail is still mostly between his legs though. I can get him to lift it when I scratch his tushie, but it immediately drops when I move somewhere else. I started him on Rescue Remedy last night. I brought him out of the bathroom for a quick walk around the house (and gave him his first dose) He saw all of my cats, and I could see he really liked the idea of other kitties. He must have been part of a clowder before coming to the shelter. I wish this were a few months ago, so I could find him a friend as I bet he'd come out of his shell a lot faster with someone to cuddle up to.
