The book My Cat Likes to Hide in Boxes was a hit with John and Suzanne — and later, their children.

Animal behavior can be fascinating. Some readers may recall my posts about foxes stealing shoes. You may also know the popular author Sy Montgomery, who interprets for the rest of us the mysterious activities of critters from the octopus to the tarantula. Meanwhile at the Washington Post, Marlene Cimons has an interesting look at household pets.

“Bella the beagle loves boxes from Amazon. She tears into them, while ignoring other deliveries. … Little Bit, a recently departed tortoiseshell cat, was similarly obsessed — but with socks. She would raid the laundry basket in the middle of the night and paw through the open suitcases of houseguests, who invariably found themselves one sock short in the morning.

“Pets do quirky things. At least it may seem that way to their humans. But these traits often make perfect sense to the pets, say scientists who study animal behavior. …

“ ‘These behaviors are not invented on the spot,’ says Carlo Siracusa, associate professor of clinical behavior medicine at the University of Pennsylvania School of Veterinary Medicine. ‘[Their ancestors’ behavior has been] adapted to their new lives as domesticated animals now that they are living with humans.’ …

“Dogs, for example, often ‘make their beds’ — as humans describe it — by scrabbling on blankets, sheets or doggy beds, then turning a few times before settling down, a habit that probably comes from an age-old instinct to create a safe, warm place to sleep.

” ‘Think about where animals sleep in nature,’ says Evan MacLean, director of the Arizona Canine Cognition Center at the University of Arizona. ‘They mat down an area before they lay in it.’ …

“Sometimes dogs will paw the ground after pooping. (Advice: Wait a few seconds before bending down to pick up their waste to avoid being hit by flying debris.) They are not burying their feces.

“ ‘They are depositing scent in those areas,’ MacLean says, which may explain their pickiness about a pooping spot. ‘They’re looking for the best part of town to put up a billboard. They want a good place to advertise. Scratching creates a ground disturbance, to catch attention. It’s almost like drawing a picture with a big red marker around it.’

“The signpost is meant for other dogs, another quirk they inherited from wolves, he says. ‘Territory marking is very likely one function of this communication, but there is a lot of other information that might be encoded in odors that we don’t understand well as humans,’ he says. …

“Cats, on the other hand, almost always bury their waste. ‘They are covering their tracks,’ says Monique Udell, director of the Oregon State University Human-Animal Interaction Lab. …

“Mikel Delgado, founder of Feline Minds, a Sacramento cat behavior consulting service, says that some of these traits derive from cats’ wild origins.

“ ‘Cats are highly predatory, they are naturally active at dawn and dusk, they are in the middle of the food chain — both hunters and hunted — with some behaviors that are natural, like scratching, and we can’t train that out of them,’ she says.

“Experts also insist that the reputation of cats as socially aloof is undeserved. They have facial scent glands, and when head-butting their human, they are probably depositing secretions to mark their social partners, says Kristyn Vitale, assistant professor of animal health and behavior at Unity College.

“ ‘Kneading’ is what kittens do to their mothers when nursing to stimulate milk production. Adult cats may ‘knead’ humans when they are feeling relaxed or are trying to calm themselves. … ‘It’s like thumb-sucking in toddlers,’ Udell says.

“While dogs share many behaviors inherited from wolves, they’ve also developed a few of their own, for example, ‘puppy dog eyes,’ the innocent look that humans are helpless to resist.

“ ‘They want to be connected to us,’ says Jeffrey Stevens, director of the Canine Cognition and Human Interaction Lab at the University of Nebraska-Lincoln. … ‘They look at us this way, and it changes our behavior.’

“Like wolves, dogs also like to lick faces. Humans think their pet is kissing them. Sorry, they are not.

“ ‘It’s how wolf puppies get food from their parents’ mouths,’ MacLean says. ‘It also can be a sign of submission. When a lower-ranking individual approaches a higher-ranking one, it gets down real low and licks the dominant one to say: “I’m not a threat to you.” ‘

“There are some behaviors researchers can’t explain, such as ‘Zoomies,’ the term often used to describe frenetic and seemingly random movement by a dog, likely an energy release.

“ ‘My dog runs around in crazy manic circles with her mouth open, her tongue out, ears back and butt tucked in, and if I mess with her while she’s doing it, she gets even more hyper,” [Sarah-Elizabeth Byosiere, director of the Thinking Dog Center at CUNY Hunter College] says. ‘She’s getting something out of her system and can’t focus until she does this. But we have zero science on this.’ “

Angie Johnston, director of the Canine Cognition Center and Social Learning Laboratory at Boston College, says that one of her dogs tap dances. ” ‘When he gets excited, he taps with his front paws, then he jumps up on all four feet and spins around in a circle in midair,’ she says. ‘He does this when he is excited or happy. I don’t know where it comes from.’

“As for Bella, the dog who preferred Amazon boxes over all others, the explanation seems to be her great success in sniffing out the snacks they contained: She smelled protein bars in the Amazon packages. After ripping her way in, she ate almost all of them, except for the few she stuffed behind the sofa cushions for emergencies.

“ ‘She was very fastidious about it,’ says Jeffrey Levi, professor of health management and policy at the Milken Institute School of Public Health at George Washington University, one of Bella’s people. ‘She never eats the wrappers.’

“Little Bit, the sock-addicted cat, was also apparently motivated by smell.

“ ‘Many animals carry around socks and shoes,’ Udell says. ‘Humans produce smells on the bottoms of their feet, so if you want to get closer to your human, there’s nothing like a good smelly sock.’ “

Wolves could be the solution to culling deer, moose, and elk that have a brain-wasting ailment. The fear is that the disease could jump to humans because cooking doesn’t kill it.

As the story goes, a wolf protected and raised the human twins Romulus and Remus, which somehow led to the founding of Rome. The notion that a wolf could suckle a human baby has a universal appeal, if not much biological support. It certainly has spawned a lot of art.

What are the chances wolves could protect us now?

Scientists concerned that a deadly cervid disease similar to ‘mad cow’ could jump to humans are asking if wolves might detect and destroy weakened animals before people can.

Jim Robbins writes at the New York Times, “Are the wolves of Yellowstone National Park the first line of defense against a terrible disease that preys on herds of wildlife?

“That’s the question for a research project underway in the park, and preliminary results suggest that the answer is yes. Researchers are studying what is known as the predator cleansing effect, which occurs when a predator sustains the health of a prey population by killing the sickest animals. If the idea holds, it could mean that wolves have a role to play in limiting the spread of chronic wasting disease, which is infecting deer and similar animals across the country and around the world. Experts fear that it could one day jump to humans. …

“Chronic wasting disease, a contagious neurological disease, is so unusual that some experts call it a ‘disease from outer space.’ First discovered among wild deer in 1981, it leads to deterioration of brain tissue in cervids, mostly deer but also elk, moose and caribou. …

“It is caused by an abnormal version of a cell protein called a prion, which functions very differently than bacteria or viruses. … The disease is part of a group called transmissible spongiform encephalopathies, the most famous of which is bovine spongiform encephalopathy, also known as mad cow disease. Mad cow in humans causes a variant of Creutzfeldt-Jakob disease, and there was an outbreak among people in the 1990s in Britain from eating tainted meat.

“Cooking does not kill the prions, and experts fear that chronic wasting disease could spread to humans who hunt and consume deer or other animals that are infected with it.

“The disease has infected many deer herds in Wyoming, and it spread to Montana in 2017. Both states are adjacent to Yellowstone, so experts are concerned that the deadly disease could soon make its way into the park’s vast herds of elk and deer.

“Unless, perhaps, the park’s 10 packs of wolves, which altogether contain about 100 individuals, preyed on and consumed diseased animals that were easier to pick off because of their illness (the disease does not appear to infect wolves). …

“ ‘Wolves have really been touted as the best type of animal to remove infected deer, because they are cursorial — they chase their prey and they look for the weak ones,’ said [Ellen Brandell, a doctoral student in wildlife ecology at Penn State University who is leading the project]. By this logic, diseased deer and other animals would be the most likely to be eliminated by wolves. …

“[Ken McDonald, chief of the wildlife division of Montana’s Fish, Wildlife and Parks Department,] said that maintaining a large enough wolf population outside of Yellowstone to control chronic wasting disease would require so many wolves that it would be socially unacceptable, especially to ranchers and hunters.

“The state’s approach to controlling the disease, he said, is to increase the number of deer that can be killed in places where the disease is growing.

“Ms. Brandell, however, said that wolves may detect the disease long before it becomes apparent to people, through smell or a slight change in the movement of prey, which could be beneficial.

“ ‘Wolves wouldn’t be a magic cure everywhere,’ [Ms. Brandell] said. ‘But in places where it was just starting and you have an active predator guild, they could keep it at bay and it might never get a foothold.’ ”

Do you know about the “Great Animal Orchestra“? Rachel Donadio at the NY Times has the story.

“The bioacoustician and musician Bernie Krause has been recording soundscapes of the natural world since 1968, from coral reefs to elephant stamping grounds to the Amazonian rain forest.

“Now, Mr. Krause’s recordings have become part of an immersive new exhibition at the Cartier Foundation here called ‘The Great Animal Orchestra.’ Named after Mr. Krause’s 2012 book of the same title, the show opens on Saturday and runs through Jan. 8, [2017].

“At its heart is a work by the London-based collective United Visual Artists, who have transformed Mr. Krause’s recordings of the natural world into 3-D renderings. Imagine stepping into a soundproofed black-box theater whose walls spring to life with what look like overlapping electrocardiograms, representing different species’ sounds. …

“The installation includes recordings Mr. Krause made in Algonquin Park in Ontario, where he found himself caught between two packs of wolves; in the Yukon Delta, a subarctic area in Alaska, where birds from different continents converge; and in the Central African Republic, where he heard monkeys. He also captured the cacophony of the Amazon, and whales off Alaska and Hawaii. …

“Mr. Krause is a polymathic musician who performed with the folk group the Weavers and helped introduce the Moog synthesizer to pop music — including songs by the Doors and Van Morrison — and film scores. He hears natural sounds with a studio producer’s ear.”

Read more here about Krause and his efforts to get the word out on the disappearing habitats of his featured animals.

This article inspires me to pay better attention to the music of the natural world on my morning walks. So much beauty goes right over my head.

In this story from radio show Studio 360, we learn that music is intriguing to animals, at the very least arousing their curiosity and perhaps stimulating and soothing them.

“Laurel Braitman is a historian of science and the author of ‘Animal Madness: How Anxious Dogs, Compulsive Parrots, and Elephants in Recovery Help Us Understand Ourselves.’ She’s particularly interested in the mental health of animals in captivity.

“ ‘If their minds aren’t stimulated, they can end up with all sorts of disturbing behaviors,’ she says. Braitman wondered if music — so often soothing to people, but usually foisted on animals without their permission — could help counter their symptoms of anxiety and depression.

“That led Braitman to arrange a series of concerts for all-animal audiences: gorillas in a Boston zoo and a small herd of bison in Golden Gate Park. Recently, the bluegrass band Black Prairie played for the residents of Wolf Haven wolf sanctuary in Tenino, Washington. …

“Can we say that they liked it?

“Researchers are trying to answer this question in controlled experiments where they observe whether animals move toward or away from speakers, depending on the music.

“Dr. Charles Snowdon of the University of Wisconsin collaborates with a composer, David Teie, who writes music tailored for certain species. They base their compositions on sonic frequencies the animals use in nature. Their music for domestic cats features tempos of purring or suckling kittens; small monkeys called cotton-top tamarins, on the other hand, got music that sounds remarkably like nails on a blackboard. ‘It is pretty godawful if you ask me,’ Snowdon says. ‘But the tamarins dig it.’ ”
