Ok, so I came home this evening around 8:30 and saw Tails on our roof! Here's a picture.
Ok, so compare this friendly cat to the one in this post. Yeah, I don't think it's Tails, but maybe it'll stick around anyway. I left some food out for it after petting it for a good 5 minutes. The boys will be so excited if he stays long enough for them to see him (or her--at the time I didn't think about checking). Anyway, have a good night!
