I found my button Silver with her head stuck between two of the top bars. I freed her but her leg is stiff and stuck out behind her, like its broken or she ripped it out of its socket while flailing around. I've moved her into her own cage separate from the other buttons but I don't know what to do. Will the vet have to amputate her leg or can it be healed? Is it likely she has a head injury since she was hanging from her head? I just don't know what to do.
