Hi. My 2 year old flying squirrel, Peanut, passed away suddenly this morning. It broke my heart. We acquired her when my cat brought her into our bedroom at 3am -- she had hair, but could not yet see, so we estimated her at about 4 weeks old at the time. I hand raised her, and she seemed quite healthy until this morning. She was eating and drinking fine last night, but I noticed this morning she was up and running around in full daylight which is unusual for her. I went to give her a treat and noticed that she was being a bit clumsy, and at some point during the night she had knocked her water bottle off of her cage. I quickly got her a bit of re-hydration solution in a syringe just to be safe, and she drank a bit. She was still trying to run around frantically in her cage though, and trying to run in her wodent wheel (which is her absolute favorite activity) but couldn't quite get it to work right. I though maybe something frightened her so I picked her up -- she was a little cooler than normal, but she didn't try to bite so I don't think she was frightened in any way. I took her out and put her in her pouch to help warm her up and offered her a small bit of apple. She is normally very greedy for treats and is actually a little on the chubby side, but she wouldn't touch it. I tried all of her favorites and she wouldn't eat. Her poop was normal, soft, and abundant, and she did pee -- though she did both in the pouch which is NOT normal for her. She wouldn't settle down, just kept turning around in circles in her pouch as fast as she could manage and then she stuck her head out and died as I was petting and trying to calm her. All of this was within about an hour. I am racking my brain to try to understand what happened -- if you have any idea... it would help to know. Nothing has changed in her cage in 2 years except the addition of the wodent wheel a month ago. She runs free around the living room pretty regularly, but unfortunately I was not able to bring her out to play for the 2 days prior to this. I have slowly been switching from guinea pig food to the deluxe squirrel diet from exotic nutrition -- she didn't like the pellets, and tended to just pick out the treats so I was trying different pellets. She has always had a calcium source to nibble on in her cage. We examined her body for any bite marks, or anything unusual -- no pests, no spider or mosquito bites, her fur was thick and healthy. No discharge anywhere. No swelling anywhere. Her eyes were clear. I just don't understand. Please help.
