Hedgehogs are certainly adorable, and it's understandably tempting to want to play with them. But what many people may fail to realize is that hedgehogs are nocturnal, which means they sleep during the day, so being handled and exposed to light during the daytime would be incredibly stressful.
"It's inhumane to subject those animals to that kind of treatment," DJ Schubert, a wildlife biologist at the Animal Welfare Institute (AWI), told The Dodo. "Hedgehogs are nocturnal, but even if they weren't, the fact that they just allow people to handle and touch and harass these animals is completely inappropriate. Some hedgehogs might acclimate to being handled, but they are, by nature and instinct, wild animals. While the animals may or may not demonstrate outward signs of stress, I can guarantee you that they're stressed."
