We hada 3-4 yr old New Zealand Rabbit that lived in a hutch outside. I had 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 Sunday night 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 had 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 was 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.The poop in the outside cage looked fine. Some were smaller than normal but solid. Monday night I brought her in and sat on the couch with her. She peed and drank a bit of water but didn't want anything to do w/food or parsley.She was dead when I woke up Tuesday morning. I have had a couple of rabbits in the past that were anywhere from a year to 4, that have died too. One day they are fine, the next, they are gone. I read that they can have digetstion issues so I made sure Raspberry had the same food and something to chew on like alfafa. I am really torn as to what happened to her. My DH suggested maybe the target shooting we did Sunday afternoon stressed her out too much.Then we had a rabbit once that lived 10 years!She was never fixed and never bred.No nasal discharge. Any ideas?
