I'm sorry, I just realized that my last message wasn't very clear
I was actually referring to raccoons the whole time (hence the 'little human-like hands' comment), cause you said they terrify you and that got me curious
As for your baby rat chasing you around and playing, that sounds so adorable!!
I'd love to see more pictures of him ! Doesn't he try to hide in the small spaces under your furniture when you let him roam freely? My hamster did that once and it took me forever to find him...
