Ludwik the Skinny Guinea PigThe rodent with no hair but plenty of style Ludwik is a “Skinny Pig” That’s a kind of guinea pig that has no hair. He’s also a STAR on Instagram! Here he is snoozing in a jumper… And wearing a very fashionable scarf! Most of the time he’s naked, though – don’t look! Although it looks like he prefers it that way! “Oi! Human! You leave my nose alone!” Hey Ludwik, the camera’s over here, mate!
