Amy hold her tail like that a LOT... The vet checked her back and tail real good the first time he saw her. There is a defect in the spine (I think he said) that causes them to hold that tail up like that. He felt up her spine and said he didn't feel that defect on Amy so he Xrayed her and it didn't show up in that either... Hers has to do with her Neroulogical disorder he decided.
