Turnip was relinquished because she was attacking the other rats in the household.  She cannot see well and has a significant head-tilt. We treated with antibiotics to rule out an ear infection so her Dr believes it could just be a permanent neurological condition.
  However, she loves to eat, lounge and customize her enclosure, all the normal rat things.  Becuase of her sight she can be grabby and nippy but once she realizes it's a hand, she lets us pet her.  We think she can do well as a single rat with an experienced owner.
