Abstract

Exurban feral cat seroprevalence of feline leukemia and feline immunodeficiency viruses and adult survival.

Abstract

Feral Felis catus (Domestic Cat) can potentially transmit feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) to other species, but seroprevalence research in exurban areas is sparse. We quantified seroprevalence of FeLV and FIV and estimated adult survival for feral Domestic Cats in an exurban city. We tested 55 cats from developed and natural habitats for FeLV and FIV and fit 31 adult cats with radiocollars for known-fates survival analysis. Combined seroprevalence (FeLV or FIV or both; 32.73%) did not differ by sex, habitat at capture location, or body condition. Annual survival was 0.86; male cats had a greater survival rate than females. Seroprevalence of FeLV and FIV in this study was greater than rates reported in other studies in the US, indicating that seroprevalence studies should be conducted at local scales.
