Lapse of Memory or Lapse of Reason?

Less than two weeks after American Bird Conservancy president George Fenwick explained in the Washington Post Magazine his organization’s position that killing cats is a moral imperative, ABC is giving a nudge to those who might be reluctant to get on board. “‘Remarkable’ deterioration in memory functions of seniors infected by common parasite found in [...]

HAHF-Truths, HAHF-Measures, Full Price (Part 3)

Complaining of the impacts of free-roaming cats on wildlife and the environment, along with a range of public health threats, dozens of veterinarians in Hillsborough County, Florida, have banded together to fight TNR. Evidence suggests, however, that their real concern has nothing to do with the community, native wildlife, or, indeed, with cats. What the [...]

Toxoplasmosis Linked to Suicide Attempts?

“There’s fresh evidence that cats can be a threat to your mental health,” according to a post on yesterday’s NPR health blog, Shots. The threat, reporter Jon Hamilton explains, is not the cats themselves by the Toxoplasma gondii parasite that some cats pass in their feces.*
“A study of more than 45,000 Danish women found that [...]

Less Toxo, More Hype

“As human populations continue to expand farther out into natural areas,” warns The Wildlife Society in a February 17 blog post, “domesticated animals will continue to be at risk for exposure to diseases carried by their wild relatives.” Considering the domesticated animals in question are cats, the organization’s apparent concern is almost touching. Almost.
Actually, TWS [...]

More Cats, Less Brain Cancer

“Evidence continues to pile up,” writes Michael Hutchins, Executive Director and CEO of The Wildlife Society, in yesterday’s blog post, “that Toxoplasmosis, a disease caused by a parasite (Toxoplasma gondii) that lives in the guts of cats, may be responsible for serious human health problems.”
Hutchins was referring to a recent study in which researchers found “Infection [...]

Loose Threads

A study published last month in the online open-access journal PLoS Neglected Tropical Diseases suggests a new twist in the relationship between free-roaming cats, Toxoplasma gondii, and toxoplasmosis infections in marine mammals.
“The most remarkable finding of our study,” notes co-author Dr. Michael [...]

Close Enough?

Among the findings of a recent study:
Five of 18 cats trapped “between the spring and fall of 2008 and 2009” in central Illinois’ 1,500-acre Robert Allerton Park tested positive for Toxoplasma gondii antibodies. Five of the seropositive cats were trapped at the same site; there, one white-footed mouse (of 21 trapped) also tested positive, and [...]

On Invasion and Persuasion

Smithsonian magazine is, according to its website, “created for modern, well-rounded individuals with diverse interests” and “chronicles the arts, history, sciences and popular culture of the times.” Jess Righthand’s recent article, “The World’s Worst Invasive Mammals,” seems—despite its inclusion in the online edition’s “Science & Nature” section—better suited for the pop culture category.
Indeed, the story [...]

Adult Supervision Required II

In my haste to get my previous post online, I neglected to address a critical point (later brought to my attention by a particularly helpful reader). So, a brief follow-up…
In “Feral Cats and Their Management,” the authors point out—correctly, in this case—that “most feral cats (62 percent to 80 percent) tested positive for toxoplasmosis.” [1] [...]

Parasite Lost

Until now, my posts have focused almost exclusively on wildlife impacts (real and otherwise) related to predation by cats, a topic I’ll be returning to soon enough. Over the past week or so, however, I’ve been researching the Toxoplasma gondii parasite (another subject that will keep me busy well into the future). As it turns [...]

Feeding Bans: Policy Hungry for Science

A recent news item from Alley Cat Allies reports “a disturbing and increasing trend of feeding ban proposals as a way to ‘eradicate’ cats from their outdoor homes.” Among the reasons cited for opposing such bans:

Cats don’t magically disappear when you stop feeding them—there’s an abundance of garbage available (from households, restaurants, supermarkets, etc.) as [...]
