So my hedgie is about 3 months old and she sleeps with me (in the same blanket) while I do my studying on the computer. Today, as she was sleeping inside the blanket on my legs, she moved around for a second and then squealed/screamed for a short time (half a second at least). Then, I suddently took her out and she started walking around and kinda coughing, but it was like grasping for air. I think she suffocated but it's not likely as I check on her like every 5 minutes. Maybe it was a nightmare? I don't really know, we always do the same thing and nothing happens. She is now fine, it was very quick and she's sleeping again like usual. Should I be worried?
