The Cat Breed With The Shortest Lifespan Is Also Known For Its 'Peach Fuzz' Fur

Hairless cat breeds are absolutely adorable. However, if you're considering adopting a furless feline for their hypoallergenic properties and general cuteness in a sweater, you may want to hold that thought to delay the worst part of pet ownership: saying goodbye. Normally, domestic cats can live for up to approximately 18 years, however, the Sphynx cat, a popular hairless breed, actually lives the shortest. 

The Journal of Feline Medicine and Surgery published a 2024 study on the lifespans of various breeds, including Sphynx cats, using sample populations of cats living in the U.K. The average cat lived around 11.74 years, with the Burmese and Birman breeds living the longest on average at 14.42 years — and the Sphynx the shortest at 6.8 years. This breed has one of the lowest life expectancies, so it may make you think twice about adopting one of these hairless treasures. However, it may also have you wondering why this is the case.

The breed's origins trace back to Ontario, Canada in 1966 with a hairless male kitten, Prune, who was born with the hairless mutation. The gene was found to be recessive, helping to develop the breed through selective breeding. However, this hairlessness is also what contributes to the sphynx's short life. While sphynx cats do have a small amount of "peach fuzz" fur, they lack the benefits that come from having a full coat. A cat's fur helps with temperature regulation as well as protecting against harmful UV rays. A hairless cat can more easily get sunburned and is more susceptible to skin cancers. This is often why cat parents purchase little sweaters for their hairless wonder. 

Sphynx cats are also predisposed to certain diseases that contribute to a shorter lifespan. The same U.K. study found that "approximately 65% of Sphynx cats aged over 4 years were diagnosed with at least one heart condition." Aside from being genetically predisposed to heart conditions, dental and skin disorders are also common. Despite this, the Sphynx cat is still a loving, sweet cat that makes for a great companion. Proper veterinary care and attention can help ensure your cat lives as long as possible.
