Are FeLV and FIV on the rise? A recent study seems to suggest yes. Here are the stats — and some reasons for the increase.

For more than a decade, researchers have tracked the prevalence of the feline leukemia virus and feline immunodeficiency virus in the United States and Canada. Recent testing of 62,201 cats — owned pets and cats in shelters — revealed that 3.1 percent tested positive for FeLV and 3.6 percent tested positive for FIV. This is an increase from the first survey done in 2006, when 2.3 percent tested positive for FeLV and 2.5 percent were positive for FIV. According to the recent study, published in the July 2017 Journal of the American Veterinary Medical Association, risk factors include outdoor access and being a sexually intact male cat.
