Adorable Hairless Guinea Pigs, Known As 'Skinny Pigs' Look Like Tiny Baby Hippos

The skinny pig is an almost hairless breed of guinea pig they typically have hair on their muzzles. But their bodies are completely hairless. The hairless strain was a spontaneous genetic mutation that was first identified at Montreal's Armand Frappier Institute in 1978.

One person commented: "Don't they get cold? How can you cuddle them? Where do you buy them? Are they hard to keep up as far as their cage? Do they bite? How long do they live? Do cats and dogs get along with them? Can they roll in those balls like the other hamsters?" Luckily, it turns out they're pretty popular, and several owners jumped into the comments to answer questions about what it's like to have one and share photos.
