I got a new bunny about 10 days ago. The pet store wasn't sure of breed, but said it was about 6 months old. They said it was a female,but I haven't had her spayed yet. She was becoming very friendly and active in her new home. I feed her timothy hay and pellets, and a small handful of parsley & a couple baby carrots for a treat every day so far. I let her out 2-3 times a day for playtime. She is eating and drinking just fine, and uses her litter box 90% of the time - everything seems normal with her potty habits. I said my usual good morning to her this morning and pet her when I fed her, and she was fine. Now I just opened her hutch so she could come out to play and her entire temperment seems to have changed. She bursted from the cage and ran around the room like she was being chased. She ran away and hid from me when I approached her. Her hutch is two levels and I was afraid she'd hurt herself running up & down like she was, so I put her away. She's hiding under the ramp to her upper level and shies away from my hand now. I have no idea what's wrong,oe why her behavior changed so suddenly. Any ideas? Please help.
