A new study published in the Journal of Feline Medicine and Surgery tried to predict the lifespans (on average) of cats in the United Kingdom. The researchers sought to quantify associations between mortality and traits such as sex, neuter status, breed status, and body weight.
The study found that life expectancy for U.K. companion cats overall was 11.74 years. Female cats (12.51 years) had a 1.33-year longer life expectancy than male cats (11.18 years). Among the 12 breeds analyzed, Burmese and Birman cats had the longest life expectancy at 14.42 years and 14.39 years, respectively. Sphynx cats had the shortest life expectancy at 6.68 years. Being intact, purebred, and of a non-ideal body weight were significantly linked to a decreased lifespan in cats.
The researchers believe these lifespan tables can contribute to a better understanding of the life trajectory of cats, helping with evidence-based decision-making for cat owners and veterinarians. The study showed evidence of the association between non-ideal weight and a decreased lifespan.ν
