When I went to check on my hedgie tonight, I noticed he didn't puff up when I went to grab him. He usually puffs up briefly then relaxes and uncurls in my hands. He used to have a room to himself, where I could make sure it was always warm and the window blinds were wide open. My uncle moved into this room, so I have to ask to go in the room just to check on him. I've noticed my uncle always has the cage all covered up and the window open. I live in the Bay Area. It gets cold at night, so it obviously hasn't been warm enough. I initially got Biggles when I lived in San Diego. My apartment was always ridiculously hot, so I never worried much about the temperature getting too cold. I'm pretty sure what happened tonight is an attempt at hibernation. He hadn't been eating or drinking as much these past two weeks, which I attributed to a new brand of food. I've had him on my lap under a blanket on a heating pad for the past 1.5 hours. He finally uncurled and is laying belly down on the heating pad. He's still pretty lethargic, but he poked his out and sniffled a bunch. He kept licking his nose, which I've read is a possible URI. I've found an exotic vet in San Francisco that I plan on taking him to first thing tomorrow morning. In the mean time, does anyone else have any suggestions for getting him through the night? I'll need to sleep at some point, although I'm much too scared to leave him alone.
