Does my Pygmy Hedgehog have Wobbly Hedgehog symptoms?

I have a 5 month old African Pygmy male Hedgehog. He was in his snuggle bag and I wanted him to go in his running ball because he hasn't for a few days now. He had to be tipped gently out the bag, even though he was clinging into it, he eventually came out. After that, he didn't move. I think I annoyed him (LOL), then he saw the running ball and climbed in it but when I put the ball on the bedroom floor, he wouldn't move atall. His quills were sticking up a little, too. He was pretty grouchy. After a few minutes, I put him back in his cage, he drank and ate then I filled his food tray up and put the lights off. He was still spiked up...and before crawling into his tunnel, he looked a little "drunk" as they say. Is it because he's cold? Apparently, they make drunk movements when they're cold. Our house doesn't have heating at the moment, but this is only for tonight. I put two shirts over his cage to prevent a draft. He eventually crawled into his tunnel then curled up into a ball after making some odd, quiet sounds here and there. After a few more minutes, he uncurled and crawled around his cage again... I'm not sure if he was walking normally because when he went on his running wheel, he didn't put a lot of effort into it at the beginning, then he walked around his cage again. He's gone back into his snuggle bag now, so I think he's warm. Are these signs of him being cold/moody/needing space/Wobbly Hedgehog Syndrome? Will he be okay?
