Free-Roaming Cats, Infectious Diseases, and the Zombie Apocalypse

A recently published paper describing free-roaming cats as “a significant public health threat” fails to deliver convincing evidence. In fact, the very work the authors cite undermines, time and time again, their claims.

“Domestic cats are a potential source of numerous infectious disease agents,” write Rick Gerhold and David Jessup, in their paper, “Zoonotic Diseases Associated with Free-Roaming Cats,” published online in July by the journal Zoonoses Public Health (and to be included in an upcoming print edition).

“However, many of these diseases are controlled in cats belonging to responsible owners through routine veterinary care, proper vaccination regimens and parasite chemotherapy. Free-roaming cats often lack the necessary preventative care to control these diseases and consequently pose a potential health threat to other domestic animals, wildlife and humans.” [1]

Just how much of a threat do these cats pose?

Gerhold and Jessup would have us believe that the risks are high and the consequences dire. A careful reading of their paper, however, reveals the authors’ tendency to cherry-pick some studies and misrepresent others. And, occasionally, simply get their facts wrong.*

All of which raises serious questions about Gerhold and Jessup’s case against free-roaming cats. Read more

Oregon Man Diagnosed with Plague

According to last Friday’s USA Today, “Health officials have confirmed that an Oregon man has the plague after he was bitten while trying to take a dead rodent from the mouth of a stray cat.”

“State public health veterinarian Dr. Emilio DeBess said the man was infected when he was bitten by the stray his family befriended. The cat died and its body is being sent to the CDC for testing.”

Other news reports suggest that the source of the bacteria—which might have been the rodent—remains uncertain. (Indeed, the fact that the cat’s body was submitted for testing suggests, that there is some question about this. The cat’s death—also unexplained—raises additional questions.)

“Humans usually get plague,” explains the Centers for Disease Control and Prevention on its website, “after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with plague.” Read more
