I used to have one! Her name was olivia abd she was dope; all she did was burrow. Inbetween the couch cushions, in clothes, everywhere. We actually lost her for a few days multiple times. They're actually awesome though cause if you're wearing cargo shorts, they'll burrow into your pocket and just chill there haha
You used to be able to get them at the pet stores around here, it wasn't anything super special. We don't really have any good pet stores anymore though, so I don't know. They're usually in the area with the Chinchillas and Guinnea Pigs and shit. My Design final was hedgehog themed, it was fucking baller.
