Lifestyle Pets Rare Male Tortoiseshell Cat Adopted from Las Vegas Shelter: 'The Unicorn of Cats' Only about 1 in 3,000 tortoiseshell cats are male By Vanessa Etienne Vanessa Etienne Twitter Vanessa Etienne is an Emerging Content Writer-Reporter for PEOPLE. People Editorial Guidelines Published on June 8, 2022 02:21 PM Share Tweet Pin Email Photo: The Animal Foundation/Instagram A rare kitten has found a forever home thanks to a Las Vegas animal shelter. On Friday, The Animal Foundation announced that its "super rare" male tortoiseshell kitten, named Comet, got adopted. Most tortoiseshell cats — a type of cat with a bicolored coat — are females, with only 1 in 3,000 tortoiseshell cats born male. According to The News & Observer, tortoiseshell cats are predominantly female because two X chromosomes are needed to produce the black and brown tortoiseshell pattern that gives the felines their name. Male tortoiseshell cats are born with an extra X chromosome. "Male calicos and torties are so rare that they are sometimes called the 'unicorn' of cats," The Animal Foundation wrote on social media alongside a sweet photo of the kitten. "Those in veterinary medicine work years or even decades without ever seeing one in person."

He was neutered on June 3 before being taken to his new home the following day. "[Comet] "spent about a month in a foster home before he was big enough and old enough to be adopted," Pizzi added.
