I have a little boy squirrel about 7 weeks old. I got him and his siblings when they were about 1-2 weeks old but the 3 others have since died. He's always been the biggest and strongest and I don't know if what's happening is life threatening or not. I haven't taken care of any animal like this before and haven't felt like this about one either. My Phantom (from Phantom of the Opera) has been making some kind of scratchy noise in his chest for about 2 days now. His breathing is kind of odd but his brother did the same thing once and all I had to do was clean his nose and he was fine. The breathing is odd because he takes deep breaths and his lungs go in a lot when he takes a breath. I can send videos of the sound he's been making and I've cleaned his nose A LOT but I can't get inside because his nose is so small. He sneezes a lot as well but usually more in the mornings I think. He eats a lot and is active so I don't think he has pneumonia and there's no clicking. I keep him warm and feed him often and he has plenty of space. I do think he is small for his age as I've seen many be bigger than a guy's hand and he still fits in mine (I'm very small) but his siblings were small too. I've read nearly everything there is know about their care and I work very hard day and night to keep him alive, as I did with his siblings. I can provide videos and pictures and can be contacted at pretty much any time. I'm very concerned about him and hope it'll clear up but he's my last little baby left and I haven't read about anyone else having these problems and I've looked up everything. Please help!
