Hey everyone! Two days ago, I started fostering or taking care of a bunny that was held at my school for this corona outbreak. But sometimes she will make these grunting, nasally, honking noises from her cage usually when I am not near her. It is an off and on sound but it can get really loud sometimes. She even does it when I'm not around. She usually stops when I get closer, but not all the time. I don't know if she is just vocal or if she is still nervous because it's a new environment. Maybe I am overthinking it but I just want to make sure she is okay. If anyone could help me out, that would be great. Thank you!
