A hedgehog has been rescued today suffering from a very unusual condition called "Pop off" Syndrome. It is a condition which is only seen in hedgehogs. It is where the main orbicularis muscle, which is responsible for helping to curl up the hedgehog, seems to slip over the top of the pelvis, sitting like a prickly hat on the back of the hedgehog. The condition disables the hedgehog which is then unable to curl up nor get around and is helpless. Caused normally by some form of trauma but in this case the cause is not known.
