I have a male hedgehog, he is 1-2yrs of age. He is usually very lively, always running on his wheel, but today I found him just layng in his cage, and when I tried to get him to move, he just layed there. I took him out of his cage and heated him up, because I thought he might have attempted to hibernate. It has been over an hour and he still can not stand or anything, he feels like a ragdoll. Also, his nose is runny. What is wrong with him? Yesterday he was perfectly fine! Please help!
