Scientists Have Composed Music For Your Cats

If your cat has ever meowed along to your favorite pop song, it’s probably not because he liked it. That music was designed in pitches and tempos that humans enjoy, so your cat is, at best, likely indifferent to your tunes (and, at worst, maybe tortured by them). Now, two psychologists at University of Wisconsin and a composer at University of Maryland have teamed up to make songs especially for your felines, with beats in the frequency range that they use to communicate with each other—and while the songs might sound unsettling to humans, research indicates that cats dig it.

The music is part of a larger project to create tunes for many members of the animal kingdom; the team has also created music for tamarin monkeys, which had a soothing effect on the creatures. The researchers hope that this species-specific music will enrich the lives of animals in captivity.

According to composer David Teie’s website, these songs are written specifically to appeal to the domestic cat, and are “based on feline vocal communication and environmental sounds that pique the interest of cats.” All of the music was made using traditional instruments and the human voice; no actual animal sounds were used.

There are three types of cat songs: Playful Kitty Ditties, which “incorporate stylizations of some of the animal calls that are of great interest to cats” and “are meant to arouse interest and curiosity”; Cat Ballads, which mimic the suckling sound, and “should be restful and pleasing for your kitty”; and Feline Airs, which are “based on the pulses of the purr” and “[draw] sympathetic emotions from the listener.” You can listen to samples of the songs here.

In their study, which was published in Applied Animal Behaviour Science, the researchers made 47 kitties listen to human music, like Gabriel Fauré's Elegie and Bach's Air on the G String, which the cats weren't into. But when they heard the feline-specific tunes, they got much more interested, rubbing their faces on the speakers.

was intrigued by this experiment, and decided to run a little experiment of my own, using my two cats, Olly and Pearl, as the guinea pigs. What would they think of the music created specifically for them? I played the songs through our TV’s sound bar and shot video, which you can see below.

Olly seemed intrigued by the music—look at how his ears move!—but not necessarily captivated by it. This could be in line with the researchers’ finding that older cats and younger cats are more likely to respond than middle-aged cats; Olly is almost 6, which, according to this chart, puts him on the cusp of “mature.” He's not a senior or geriatric yet (although he does act like a grumpy old man sometimes).

Pearl, on the other hand, is 1.5 years old, a “junior,” and she really enjoyed the cat tunes. The only things she meows for more is her food and the string we use to get her to run around our apartment (she’s a lazy little kitty with a big appetite). When I played the music for her again this morning, this time on my laptop, she stalked around it, rubbing her face against the edges of the screen and occasionally trying to take a bite (bad Pearl!). As a cat who was likely feral before she was surrendered to a shelter, Pearl can sometimes be standoffish, but I noticed that she became more affectionate during certain songs. And because I'll do anything for a cuddle, I’ll be downloading any cat songs Teie creates in the future—and not just for Pearl and Olly. I found that, after listening to them long enough, they became kind of soothing for me, too.

The Simple Way to Protect Your Dog From Dangerous Rock Salt

Winter can be a tough time for dogs. The cold weather usually means there are fewer opportunities for walks and more embarrassing accessories for them to wear. But the biggest threat to canines this time of year is one pet owners may not notice: the dangerous rock salt coating the streets and sidewalks. If you live someplace where this is a problem, here are the steps you need to take to keep your pooch safe until the weather warms up, according to Life Hacker.

Rock salt poses two major hazards to pets: damage to their feet and poisoning from ingestion. The first is the one most pet owners are aware of. Not only do large grains of salt hurt when they get stuck in a dog’s paws, but they can also lead to frostbite and chemical burns due to the de-icing process at work. The easiest way to prevent this is by covering your dog’s paws before taking them outside. Dog booties get the job done, as do protective balms and waxes that can be applied directly to their pads.

The second danger is a little harder to anticipate. The only way you can stop your dog from eating rock salt from the ground is to keep a close eye on them. Does your dog seem a little too interested in a puddle or a mound of snow? Encourage them to move on before they have a chance to take a lick.

If, for some reason, you forget to follow the steps above and your pet has a bad encounter with some winter salt, don’t panic. For salty feet, soak your dog's paws in warm water once you get inside to wash away any remaining grit. If your dog exhibits symptoms like vomiting, diarrhea, and disorientation and you suspect they’ve ingested rock salt, contact your vet right away.

Even with the proper protection, winter can still create an unsafe environment for dogs. Check out this handy chart to determine when it’s too cold to take them for a walk.

Boston's Museum of Fine Arts Hires Puppy to Sniff Out Art-Munching Bugs

Some dogs are qualified to work at hospitals, fire departments, and airports, but one place you don’t normally see a pooch is in the halls of a fine art museum. The Museum of Fine Arts, Boston is changing that: As The Boston Globe reports, a young Weimaraner named Riley is the institution’s newest volunteer.

Even without a background in art restoration, Riley will be essential in maintaining the quality of the museum's masterpieces. His job is to sniff out the wood- and canvas-munching pests lurking in the museum’s collection. During the next few months, Riley will be trained to identify the scents of bugs that pose the biggest threat to the museum’s paintings and other artifacts. (Moths, termites, and beetles are some of the worst offenders.)

Some infestations can be spotted with the naked eye, but when that's impossible, the museum staff will rely on Riley to draw attention to the problem after inspecting an object. From there, staff members can examine the piece more closely and pinpoint the source before it spreads.

Riley is just one additional resource for the MFA’s existing pest control program. As far as the museum knows, it's rare for institutions facing similar problems to hire canine help. If the experiment is successful, bug-sniffing dogs may become a common sight in art museums around the world.
