I have a 3 yr old New Zealand Rabbit that lives in a hutch outside. I have old hay in the hutch for bedding. It isn't moldy, just too dry to be fed to horses. I noticed that she hasn't eaten anything since yesterday and seems very sad. Definitely not feisty like normal. Nor did she have any interest in running around when I let her loose for a while. She has been fed her rabbit feed and the weeds I normally pick from the grass for her. She has eaten the weeds for a couple of years and no we don't chemically treat. While it has been about 40-50 at night, I'd think she is staying pretty warm inside of the hutch. I know nothing of where she was born or came from. She was left by the renters at our old house. We got her when she was a few months old. Any idea on what can be wrong with her?
