I thought she looked abit like a wild rabbit, I think he's a she meant to be about 18 months definatly no dangley bits although the woman he came from said its a boy so he's gone from Buster to Hoodie and now Mika. She's been in a shed most of her life in an small indoor cage very boney although doesn't look too bad in the photo. She is really friendly and i think you are right about jumping and running (My other rabbit Tango is the complete opposite but i hope to bond them eventually) going to have to watch out when she's fitter when she first came she fell over when she tried to stand up but she's got the hang of it now.
