A little backstory: We have 2 bunnies, and our Izzy is around 14-16 weeks old. We got her and one of her littermates in early April, and the other one suddenly passed away 3 weeks ago. I went in there to let them out of their cage and she was laying there dead.
It was horrible, and we have no idea what happened to her. She had no symptoms and went from happily hopping around to dead within a couple of hours. Izzy was so sad, so we got another buddy (Cubby) for her.
When I woke up this morning, one of Izzy's ears was completely flopped over. It just hanging there limply. It was fine yesterday. Is this ever normal? I am so scared that something will happen to her too, so I am a little paranoid. Please help!
