well I wish I had some wisdom for you,the only suggestion would be to ask your vet - maybe she is sick or something. I just wanted to say that I hope you can figure out what's going on with her - have you gotten her fixed? Maybe if she's not would that have something to do with it? It might be a behavioral problem or something that maybe the vet can help you with. I just wanted to wish you Good luck! and hope everything turns out ok
