On October 15, 2020, Peru’s Ministry of Culture announced that a new carving, called a geoglyph, had been discovered at the Nazca lines site (5). The surprise addition was a cat–a very, very old one. The Nazca lines as a whole are an archeological wonder and a mystery. Yet the cat on the hill is a unique specimen among the titanic works of human ingenuity on display.

What Are the Nazca Lines?

The Nazca lines are a series of designs carved into the ground of the Peruvian coastal plain. Each design is called a geoglyph. Although other places around the world have geoglyphs, the Nazca lines site is among the most famous, and possibly the largest. The geoglyphs are scattered over approximately 450 square km (174 square miles) of desert (7). The geoglyphs include straight lines, over 800 of them, some of which are 48 km (30 miles) long; simple shapes and designs such as triangles and spirals; and a smaller number of animal, plant, human, and fantastical figures (1, 2, 4, 7)

Three groups of people are believed to have made the Nazca lines: the Chavin, Paracas, and Nazca cultures (6). Archeologists think the Nazca made most of the geoglyphs around 200 B.C. to 700 A.D. (1-3, 7). The Chavin and Paracas were earlier contributors (2, 7). There is no consensus as to why they made these massive works of art, but it must have been important to them, because it wasn’t easy.

To make these geoglyphs, the ancient artists removed 12 to 15 inches of reddish, iron oxide-coated pebbles to uncover the layer of sand below (2, 6). The designs are so big, they can’t be seen in their entirety from the ground, so the project required a lot of planning and cooperation. It must have taken a long time, but their work had staying power. Because the Nazca lines were carved into one of the driest places on the planet, they have held up for 2000 years (2).

As to the possible motive for such an undertaking, there are plenty of theories. An early theory proposed that the geoglyphs served an astronomical and calendrical function (1, 2, 7). Later researchers moved toward other theories, i.e. that the geoglyphs were part of a religious rite to bring water or fertility (2). Alternatively, the designs may have been signposts and ritual sites for pilgrims (1, 2). Experts in other fields have offered different explanations. I’ve heard it said that the Nazca lines were made as landing strips for alien spacecraft. Archeologists reject such claims.

A New Discovery

Although the Nazca lines have been under study since they were found almost 100 years ago, new geoglyphs are still discovered all the time (1, 4, 6). Usually, it is due to the efforts of the site’s researchers, but happy accidents happen, too. A crew was remodeling El Mirador Natural viewpoint when something on the hillside caught the eye of the supervising archeologists (5). With careful cleaning, the figure emerged. The 37 m (120 ft) long cat appears to be either laying on its side or standing in profile (1, 3, 5, 6). It has large, round eyes and a striped tail (1, 4).

Unlike most of the geoglyphs, the cat on the hill is not thought to have been carved by the Nazca people (3, 5). It dates to between 200 and 100 B.C., making it to oldest geoglyph yet discovered at the Nazca lines (1, 4, 6)! That also makes it older than the Nazca people. Rather, the cat appears to be the handiwork of the Paracas culture (1, 3). They were around right before the Nazca, and the geoglyph matches the style of cats depicted on Paracas textiles and ceramics (1, 3).

We nearly lost this unique geoglyph before it was even found. According to Peru’s Ministry of Culture, “The figure was scarcely visible and was about to disappear, because it’s situated on quite a steep slope that’s prone to the effects of natural erosion” (5). And geoglyphs are extremely delicate. The reason the Nazca lines site has viewpoints in the first place is because a single footprint can irreparably damage a geoglyph (1, 4). Visitors are only allowed to view the designs from the designated viewpoints or from the air. Fortunately, no one accidentally destroyed this incredibly cool cat before it could be found and conserved.

What Cat is That?

There were no domestic cats in South America at the time the cat on the hill was etched into the earth. Which cat were the Paracas people commemorating, then? There’s no way to know for sure. It isn’t exactly a true-to-life representation. But I fell down a bit of a rabbit hole anyway. According to the International Society for Endangered Cats, there are nine small wild cats and two big cats. That’s according to size, not taxonomy. Much to my amusement, the top comment on the ISEC page for South America was somebody asking exactly this question. They didn’t get a clear answer, though, which meant I had to keep digging.

The geoglyph cat’s proportions and tall, pointy ears don’t seem much like either of the big cats, jaguar or puma. Besides, pumas don’t really have stripe-y tails. So, on to the small cats. Range and habitat can exclude a few. Andean cats live high in the Andean mountains. The kodkod only lives in forests in Chile. Margays and northern tiger cats are found in the interior forests. Southern tiger cats are too far south, oddly enough. That leaves the ocelot, Geoffrey’s cat, jaguarundi, and pampas cat.

Jaguarundis have short, round ears, no stripes, and kind of squinty eyes. Seems improbable. The other three are all reasonable candidates. I lean toward the pampas cat. The body shape looks a lot like the geoglyph, not just the eyes, ears, and stripes. So that’s my best guess, if anyone was wondering other than me. I think the Paracas people inscribed a 37-m pampas cat into a hillside. No one knows exactly why, but if you were going to put all that work into drawing something, it might as well be a cat.

How do cats use their whiskers?

Whiskers, known in the scientific world as vibrissae, are sense organs common among mammals. Because humans completely lack these specialized hairs, it is difficult, if not impossible, for us to really understand what animals that have them experience. It is a completely different, sixth sense that enables them to learn about their environment in a way that we cannot. Research has given us mere humans insight into how whiskers function, though, and how to be considerate of our furry friends’ precious whiskers.

Whiskers on Kittens

A whisker is a long, thick hair, which grows from a hair follicle like a cat’s fur does (2, 4). However, the hair follicles that make whiskers are different from the ones that make fur in a few important ways. For one, whiskers are rooted three times deeper into the skin than regular hairs (2, 6). The follicles for whiskers also have far more blood vessels and nerves (2, 4, 6). This heightens the sensitivity of the individual whisker hairs.

Cats have whiskers on their muzzles, chins, and forelegs; above their eyes; and near their ears (2-6). The number and length of whiskers varies. Most cats have 12 whiskers on either side of their noses (2, 6). Whiskers are usually light in color, but some cats may have black or brown whiskers, or a mix of colors. The color of a cat’s whiskers may even change over their lifetime (6, 7).

How Do Whiskers Work?

Although whiskers are sometimes called tactile hairs, the whiskers themselves don’t have any sense of touch. Rather, the movement of the whiskers triggers the nerves in the hair follicle, and that information is sent to the brain (2, 4, 5). This can tell a cat about the location, size, movement, and texture of an object as well as more general environmental information (2-5).

On the end of each whisker is a tiny organ called a proprioceptor (2, 4). Proprioceptors detect vibrations in the environment (4). They enable a cat to sense the position of its own body and all the components thereof in space (2, 4).

What Are Whiskers For?

Animals use whiskers for a lot of different things. Scientists have discovered that, depending upon the species, whiskers are involved in “food acquisition, prey attack, aggression and attack behavior, facial expression in intraspecies communications, dispersion of pheromones, maintaining head position in swimming, and a wide range of environmental monitoring (e.g. current detection in water, wind direction on land)” according to A. S. Ahl (1). Even in cats alone, whiskers serve a variety of functions.

Cats are somewhat farsighted. Whiskers compensate for the trouble cats have focusing on objects close-up (2, 6, 7). This can be particularly important for hunting. Once a cat pounces on their prey and has it in their paws, their whiskers help them “see” to tussle with it and deliver the fatal bite (2, 4, 6). Many of the animals cats prey on also have whiskers, though, which can help them to sense cats coming (5).

A cat’s whiskers tell them if they can fit into a space or not (2, 4, 6, 7). Their muzzle whiskers are as long as they are wide (4, 6), so whether the whiskers bend when a cat puts its head in a space tells it if the rest of its body will fit. Whiskers don’t just protect cats from getting stuck in tight places, though. They also protect delicate parts of their bodies from damage (2). The whiskers on the face, especially those above the eyes, alert cats to objects that pose an imminent risk to their eyes (2). Whiskers can detect trouble as small as a speck of dust.

Whiskers serve a social function, as well. Cats communicate with each other mostly through body language. We can learn to understand these messages, too. The position of a cat’s whiskers provides one clue to their emotions. If your cat is relaxed, her whiskers will be as well, sticking straight out to the sides (4, 6). If they are excited, curious, or alert, they’ll push their whiskers forward (2, 4, 6). A cat that is angry or scared will pin their whiskers back against their face (4, 6).

Whisker Do’s and Don’ts

DO be mindful of whisker fatigue. Whisker fatigue is the pain and stress cats experience when their food and/or water bowls regularly brush up against their sensitive whiskers (3, 4). Tall, narrow bowls tend to be the culprit (3, 4). Be kind to your cat’s whiskers, and use wide, shallow bowls instead (3, 4, 6). Symptoms of whisker fatigue include:

  • Scooping food out of the bowl and eating on the ground
  • Making a mess while eating/drinking
  • Leaving food in the bowl but acting hungry
  • Approaching the food/water bowl with caution; pacing nervously before eating/drinking
  • Refusing to eat unless the bowl is full
  • Mealtime aggression (3)

DON’T cut your cat’s whiskers, ever. Number one, it’s painful for them (7). Number two, it disorients and confuses them (2, 4, 6, 7). For blind cats or cats that spend time outside, that is extra dangerous. There is no health reason to trim a cat’s whiskers, and it is not worth it just for aesthetic reasons.

DO check with your vet if you feel like your cat is losing a lot of whiskers. Whiskers fall out and are replaced when they get old just like any other hair. However, losing many whiskers in a short period of time can be an indication that something is wrong. Numerous skin conditions such as acne, allergies, and infections can cause whisker loss (7). So if your cat is losing whiskers frequently or en masse, consult your veterinarian (7).

DON’T play with a cat’s whiskers. Whiskers are cute, and it’s tempting to touch them, but most cats will find anything more than a gentle stroking uncomfortable. If you find a shed whisker, however, go nuts. I have a friend that uses her cats’ shed whiskers as tiny paintbrushes.

Fun Facts

  • Some cats may have curly whiskers, especially if they are of a curly-coated breed.
  • The word “whisker” dates back to about 1600. It comes from the Middle English “wisker,” meaning anything that whisks or sweeps. (4)
  • Each individual whisker can be traced to a specific spot in a cat’s brain. (2)
