We recently got a hedgehog who is 2.5 years old. We got her from another family who didn’t have much time to spend with her. We have been spending about an hour every night reading to her and letting her run around by us. Just last night she was sitting in one spot for a while and decided to curl into a ball. While she was in the ball she was making a movement that almost seemed like a convulsion. Like a body would look like when vomiting. Any ideas? Should we be worried? She did this three times for about 5 seconds each and about 30 seconds apart.
