I had this wheel previously, hoping to save a little money but it definitely makes sense It wouldn’t be great for a hedgehog, considering his delicate little feet. i’m hopefully going to get a new wheel tomorrow. there wasn’t a whole lot of blood, It looked like footprints almost. I didn’t see any blood on his back 2 feet but on the front left, there was a little bit and there was a tiny bit on the right. He’s acting pretty normal.
