Nationwide, unaltered cats have shorter life spans, Banfield Pet Hospital reported Wednesday in its 2013 State of Pet Health Report.
The annual survey, which also looked at the most common diagnoses and other statistical trends of cat and dog health, was based on data compiled from visits by 2.2 million dogs and 460,000 cats to Banfield hospitals in 2012.
2013 Dog and Cat Study Difference
“This year’s report is focused on the overall life span of pets … state by state … as well as factors that may influence life span,” stated Marta Monetti, senior vice president of corporate affairs at Portland, Ore.-based Banfield.
The difference in life spans was attributed to whether a cat or dog was sterilized.
Neutered cats lived, on average, 62% longer than unneutered males, the Banfield data revealed. Spayed cats lived 39% longer than unspayed female cats. For dogs, neutered males lived 18% longer. Spayed females enjoyed a 23% advantage.
