The Science Behind the Urge to Cuddle Cute Babies

You don’t have to be a cat person to feel your heart warm up at the sight of a big-eyed, tiny-nosed kitten stumbling across the floor. When confronted with a baby kitty, you may feel the urge to scoop it up and cuddle with it for the rest of the day. This reaction isn’t limited to felines—puppies and even some adult animals trigger these same snuggle instincts. If this feeling sounds familiar, that means your brain is just doing what it evolved to do to preserve the human species.

This episode of the National Geographic video series We’re Wired That Way lays out what's going on in your head when you see something cute. The facial features of most young mammals fall into the same configuration: large round eyes, and small noses, mouths, and chins. This is called kinderschema, and humans are engineered to find it adorable because it can be found in our own babies. When we see a typical baby face, it activates our instincts to nurture and protect while also releasing the feel-good chemical dopamine to reward us for doing so. That way we feel driven to keep babies safe even if they’re not our own, thus boosting their chances of survival and the survival of our species.

Because kinderschema isn’t limited to the human race, we feel this response when looking at non-human baby animals as well. Some mammals, like cats and guinea pigs, retain their kinderschema into adulthood. So next time you let out an involuntary squee at the sight of your pet, remember that you have biology to blame.

Bleat Along to Classic Holiday Tunes With This Goat Christmas Album

Feeling a little Grinchy this month? The Sweden branch of ActionAid, an international charity dedicated to fighting global poverty, wants to goat—errr ... goad—you into the Christmas spirit with their animal-focused holiday album: All I Want for Christmas is a Goat.

Fittingly, it features the shriek-filled vocal stylings of a group of festive farm animals bleating out classics like “Jingle Bells,” “Rudolph the Red-Nosed Reindeer,” and “O Come All Ye Faithful.” The recording may sound like a silly novelty release, but there's a serious cause behind it: It’s intended to remind listeners how the animals benefit impoverished communities. Goats can live in arid nations that are too dry for farming, and they provide their owners with milk and wool. In fact, the only thing they can't seem to do is, well, sing. 

You can purchase All I Want for Christmas is a Goat on iTunes and Spotify, or listen to a few songs from its eight-track selection below.

If You Want Your Cat to Poop Out More Hairballs, Try Feeding It Beets

Have you ever wondered if there’s a way to get your cat to poop out its hairballs instead of hacking them up? If so, you’re likely a seasoned cat owner whose tolerance for gross stuff has reached the point of no return. Luckily, there may be an easy way to get your cat to dispose of hairballs in the litter box instead of on your carpet, according to one study.

The paper, published in the Journal of Physiology and Animal Nutrition, followed the diets of 18 mixed-breed short-haired cats over a month. Some cats were fed straight kibble, while others were given helpings of beet pulp along with their regular meals. The researchers suspected that beets, a good source of fiber, would help move any ingested hair through the cats’ digestive systems, thus preventing it from coming back up the way it went in. Following the experiment, they found that the cats with the beet diet did indeed poop more.

The scientists didn’t measure how many hairballs the cats were coughing up during this period, so it's possible that pooping out more of them didn’t stop cats from puking them up at the same rate. But considering hairballs are a matter of digestive health, more regular bowel movements likely reduced the chance that cats would barf them up. The cat body is equipped to process large amounts of hair: According to experts, healthy cats should only be hacking hairballs once or twice a year.

If you find them around your home more frequently than that, it's a good idea to up your cat's fiber intake. Raw beet pulp is just one way to introduce fiber into your pet's diet; certain supplements for cats work just as well and actually contain beet pulp as a fiber source. Stephanie Liff, a veterinarian at Pure Paws Veterinary Care in New York, recommends psyllium powder to her patients. Another option for dealing with hairballs is the vegetable-oil based digestive lubricant Laxatone: According to Dr. Liff, this can "help to move hairballs in the correct direction."
