Lindsay,
Im also lead to believe that it is a rabbit, This had been beatin to death by MANY different forums and expirenced herp keepers, and no real answered has poped up yet, But considering the tail and the chacteristics of the hind leg, it makes me lean towards a rabbit. Also the head is very small.

My intent wasn't to start another debate, Like i said this topic has already been beatin to death , So i guess it will always stay a mystery until we can get in conatct some how with the owner
