I'm sorry to hear this. I would also try buying a few feliway plugins. You can also buy the spray too. I've been using these and a similar item that I buy at Petsmart and they really seem to help to destress my furkids. Storms also on an herbal calming pill to help his aggressive behavior. I call it his chill pill and it helps him a lot. I hope she'll start feeling better soon. Good luck.
