In celebration of World Animal Day, Guinness World Records today announces that Fizz Girl, a Munchkin Cat from California, has grabbed the record title for 'Shortest Living Cat'.

Measuring in at just 6 inches tall, this diminutive puss has earned herself a coveted spot in the new Guinness World Records 2012 Edition.

Fizz Girl is of the Munchin Cat breed, in which cats are born with unusually short legs.

People often mistake Fizz Girl as a kitten, rather than an adult cat.

Hailing from Southern California, the tiny three-year-old cat doesn't get the "short end of the stick."

Owner Tiffani Kjeldergaard says: "Fizzgirl knows that she's short, but she has no problems climbing and getting to the highest places in the house."

She goes on to describe the cat as a 'princess' but also a very loyal and loveable companion.

Though Tiffani has bred Munchkin Cats for years, she has never seen one quite as small as Fizz Girl.

She takes the title from predecessor, Itse Bitse, a Himalayan/Siamese mix who measured 3.75 inches high but then went missing.

Fizz Girl is already a hit sensation online and is YouTube's 5th most viewed 'Pets and Animals' video worldwide with 312,928 views.

World Animal Day was started in 1931 at a convention of ecologists in Florence as a way of highlighting the plight of endangered species. Since then it has grown to encompass all kinds of animal life and is widely celebrated in countries throughout the world. October 4 was chosen as World Animal Day as it is the Feast Day of St Francis of Assisi, the patron saint of animals.
