A zoo in Japan recently placed a bristle brush inside their hedgehog exhibit, along with the message stating that due to the cold weather, the hedgehog is staying inside a custom warm enclosure (possibly hibernating?), so they have prepared the brush there as a substitute “because they all look the same anyway. Hedgehog will be back when the weather becomes warm again”.
Thankfully, the zoo is free to attend to begin with, so there’s not much of a loss to the guests. Some people have also claimed that the hedgehog can still be seen in the enclosure with the red wooden frames in the rear of the picture, though I personally don’t see it. Picture first found on twitter.
