Conventional wisdom would suggest that all dogs love to play fetch, while most cats would simply refuse to do so. But a new paper published in the journal PLoS ONE suggests that cats not only play fetch with their owners, they do so far more frequently than previously believed. And while most dogs play fetch at least sometimes, about 12 percent do not. More-trainable dog breeds are more likely to exhibit fetching behavior, while in both species, animals that are more active and playful—and usually male—are more likely to enjoy playing fetch, suggesting that it is a form of play.

"We were surprised to find that there were very few studies of fetching behavior in dogs," said co-author Mikel Delgado, a veterinary medicine researcher at Purdue University. "And personally, as a life-long cat person, I have to admit that I thought all dogs fetched. So it was interesting to get a better sense of how common this behavior is in cats and dogs. We hope that the study draws more attention to fetching behavior in cats, who are often portrayed as independent and aloof. In fact, they can be very social, and this is a nice example of one way they are interactive with humans."

As previously reported, many different animal species exhibit play behavior, and it's most common in mammals and birds. Contrary to what one might expect from cats, fetching behavior has been observed across multiple cat breeds all over the world, usually emerging in kittenhood. One owner who participated in a 2022 study noted that their cat was so obsessed with fetch that it would sometimes drop its favorite toy on their face in the middle of the night.

Ah, cats. We love our furry feline overlords despite the occasional hairball and their propensity to scratch the furniture to sharpen their claws. The latter is perfectly natural kitty behavior, but overly aggressive scratching is usually perceived as a behavioral problem. Veterinarians frown on taking extreme measures like declawing or even euthanizing such "problematic" cats. But there are alternative science-backed strategies for reducing or redirecting the scratching behavior, according to the authors of a new paper published in the journal Frontiers in Veterinary Science.

This latest study builds on the group's prior research investigating the effects of synthetic feline facial pheromones on undesirable scratching in cats, according to co-author Yasemin Salgirli Demirbas, a veterinary researcher at Ankara University in Turkey. "From the beginning, our research team agreed that it was essential to explore broader factors that might exacerbate this issue, such as those influencing stress and, consequently, scratching behavior in cats," she told Ars. "What’s new in this study is our focus on the individual, environmental, and social dynamics affecting the level of scratching behavior. This perspective aims to enhance our understanding of how human and animal welfare are interconnected in different scenarios."

The study investigated the behavior of 1,211 cats, with data collected via an online questionnaire completed by the cats' caregivers. The first section collected information about the caregivers, while the second asked about the cats' daily routines, social interactions, environments, behaviors, and temperaments. The third and final section gathered information about the frequency and intensity of undesirable scratching behavior in the cats based on a helpful "scratching index."

For more than a decade, in blog posts and scientific papers and public talks, the psychologist Hal Herzog has questioned whether owning pets makes people happier and healthier.

It is a lonely quest, convincing people that puppies and kittens may not actually be terrific for their physical and mental health. “When I talk to people about this,” Herzog recently said, “nobody believes me.” A prominent professor at a major public university once described him as “a super curmudgeon” who is, in effect, “trying to prove that apple pie causes cancer.”

As a teenager in New Jersey in the 1960s, Herzog kept dogs and cats, as well as an iguana, a duck, and a boa constrictor named Boa. Now a professor emeritus at Western Carolina University, he insists he’s not out to smear anyone’s furry friends. In a blog post questioning the so-called pet effect, in 2012, Herzog included a photo of his cat, Tilly. “She makes my life better,” he wrote. “Please Don’t Blame The Messenger!”
