I'm sure that since this video aired two years ago, another teeny cat has come to replace Mr. Peebles in the Guinness World Book of Records as the world's tiniest cat. But let's give this little guy his due, shall we? In this clip, he's two years old, and yet weighs only three pounds. Apparently, his original owner didn't love him (!!), so a veterinarian with a soft spot for Mr. Peebles took him in. (Click here to read more about his saga.) My favorite part of the story? When the vet saw him, he asked the owner, "Can I have him?" She replied, "If you can catch him." Cute!
