Just now, I was sitting next to my hedgehog's cage watching her run around, and she was fine with me being there. Then she started eating and I moved a little bit. When I moved, she completely froze, mouth open, still with food in it. I froze myself for about 2 minutes in hopes that she would go about her business and she didn't. I then picked her up (she did not huff or anything which was very strange) and she curled into a ball. She has never stayed in a ball for more than 30 seconds but this time she stayed curled for a few minutes and didn't huff at me when I would pet her quills. Eventually, she came to and started moving around again so I put her back in her cage but then a few minutes later she froze up again when I moved. Has this ever happened to anyone else? I'm not concerned, only wondering what just happened!!
