2-Faced Cat Named Frank and Louie Dies at Age 15

1 minute read

The two-faced cat, named Frank and Louie, has died at the ripe old age of 15.

Frank and Louie was rushed to the Cummings School of Veterinary Medicine at Tufts University, where he was diagnosed with a “really bad cancer,” said the cat’s owner, Marty Stevens. Stevens then agreed to have Frank and Louie euthanized, the Telegram of Worcester reported Thursday.

Janus cats, so-called after the two-faced Roman god, usually live for only a few days. The phenomenon doesn’t actually result from what causes conjoined twins — the incomplete separation of two embryos — but instead from the abnormal activity of a protein, which leads to duplication of parts or all of the face.
