We have a fairly new little girl--Chloe--whose background is a bit vague. We know she was abandoned by a family who moved, and she appears to have gone through a bit of neglect. She's very sweet, loves tummy rubs and petting, but she has a behavior I've never seen in my other two cats--she pets herself. She'll lie on her back and stroke her own head and under her chin with her paw. Not in a cleaning fashion--she does groom, but this action is different, she pets herself just like a human would pet her. I'm wondering about the origin of this behavior--has anyone seen anything like this from a previously neglected or abused cat?
