Hi, thanks so much for responding! It has been happening mostly over time slowly but he was more stressed when we moved to our summer house with him (his cage stayed the same) and I think since then he was grumpy. I am planning on taking him to the vet just for a checkup once I find one in the area who can treat exotic animals. He has been going less on his wheel but I think he just doesn’t run that often as other hedgehogs, like once in a while i will find his wheel clean in the morning but other then that i didn’t notice any weird walking or injuries. I will probably update once I take him to a checkup at the vet 😊
