One of the admittedly not-so-cute hedgehog behaviors that baffle;many new owners is self-anointing. Your hedgehog will be going about its usual business when it suddenly stops, works up a mouthful of frothy saliva, and then uses its tongue to spread the foam all over its quills, generally contorting and twisting wildly while doing so. While it looks like a seizure, this is actually normal hedgehog behavior. Although no one is certain why hedgies self-anoint, it tends to happen most often when they encounter a new scent, and it may be a protective behavior.
