Sorry you might have to get rid of her. Maybe phone your vet and ask if there are any bunny rescues in your area. Someone might be able to help. I had a female bunny a long time ago and she was aggressive too. I have a male now and he is sweet as ever. I know Miss Hoppy's a girl and I don't think shes aggressive.Good luck with whatever you choose, but try to find her a home before resorting to euthanizing her. Maybe someone from PT lives in your area. Post in pet general.
