Pet cats that roam outdoors can carry similar disease risk as feral cats

Phys · · 560 words · By University

A new study analyzing data from 88 countries found that pet cats allowed to roam outdoors carry infectious diseases at rates comparable to feral cats, even if they receive veterinary care. Researchers suggest that public health efforts should broaden their focus beyond only feral cats to address the risks posed by owned, roaming pets. The article recommends preventative measures like enclosed patios and harnesses to reduce zoonotic exposure.

“Cats are documented to kill over 2,000 wildlife species worldwide, with small mammals—common carriers of disease—among their most frequent prey.”
