A Guinness World Record holder, the cat passed away at the Cummings School of Veterinary Medicine at Tuft's University yesterday after veterinarians euthanized him as he was suffering from a "really bad cancer", owner Martha "Marty" Stevens of Worcester, Massachusetts said.
Frank and Louie had been "a little down" around Thanksgiving and she was administering some fluids, but yesterday morning it appeared the cat was getting sicker and she raced to Tufts, Stevens told the Telegram newspaper.
While she is devastated, Stevens said she knows the cat initially had no chance at all after being brought into the clinic to be put to sleep in September of 1999. Janus cats typically do not live more than a few days and are often rejected by their mothers.
Frank and Louie had two functioning eyes and a center eye, which was blind. Two noses and two mouths but just one brain. All in all, he was a healthy cat, his biggest ordeals having been neutering and the removal of some teeth from Louie's mouth, which had no bottom jaw.
While she is reeling from the unexpected death of her pet, she said she will do it all again and would take a Janus cat in if one was in need.
"I would love to do it again," she said.
