Current Record Holder: Mr. Peebles

The current world’s smallest living domestic cat listed in the Guinness World Records is a 6.1-inch tall 3 pounder named Mr. Peebles from Good Shepherd Veterinary Clinic in Pekin, Illinois co-owned by employees from the clinic. The reason he looks like a kitten even though he is an adult cat is due to a genetic defect that hampered his growth. Despite his stature, he has a huge appetite and requires four meals a day to sustain his life.

Maybe the Next Smallest Cat: Bitsy

However, the current record holder may be over taken by a full grown tuxedo cat who weighes merely 1.5 lbs. Bitsy, the kitten-like fluff ball from San Diego, is a healthy cat albeit her size. She has good spirits and enjoys taking rides with her human mother.

Bitsy, a cross breed between a Munchkin and a normal sized cat, suffered from a mutated gene that is the same as that of little people, but usually Munchkins with a mutated gene weigh between 3 and 5 lbs. Bitsy was born with a big head that was supported by a tiny body.
