Imagine if there was someone out there old enough to have lived through all the biggest events of the 19th and 20th centuries. Someone who’d not only been around at the advent of spaceflight, but of powered flight itself! Well, such a being does indeed walk this Earth, but he’s not a human. He’s a tortoise named Jonathan, and he just celebrated his 190th birthday with one “shell” of a party. 

Stary Oskol is a little-known Russian town with a growing claim to fame: its hairiest inhabitant, Kefir. His human, Yulia Minina, got him as a tiny kitten — at least, that’s what she thought — less than two years ago. Now Kefir is a huge bundle of fur that weighs more than a small child, and he’s still getting bigger! But the question is, what exactly is Kefir? And how large can we expect him to get?
