Think of your favorite food. Imagine the cheesy or chocolaty or crispy delight. You might want to eat that food forever and ever. You might want to roll around in that food and change your name to that food. (Okay, maybe that’s a little too far.) But cats feel that strongly about a particular treat. They might not want to roll around in pizza or chocolate cake. But, they may want to roll around in their favorite herb: catnip. Catnip is a strong-smelling plant that many cats love to sniff. When exposed to catnip, a cat might rub its head and body on the herb, roll around in it, chew it, meow, and generally act crazier than usual. In addition, new research from Japan suggests that all that rolling around in catnip actually has health benefits for cats. Chemical compounds in catnip may help our feline friends ward off mosquitoes, pesky insects whose bites can transmit heartworm infections in cats.

The way in which scientists came to this conclusion may surprise you. No, researchers did not invite a dozen or so cats to a camping weekend. They did not give the cats supplies for feline-friendly s’mores—made with catnip and tuna sandwiched between kibble crackers. Researchers did not then examine whether mosquitos munched on cats while they told ghost stories around a campfire. No, none of this happened.

Instead, researchers gave some cats scraps of paper soaked with iridoid, a chemical in catnip that affects pleasure areas in the cat’s brain. The cats then rolled around in these slips of paper, reveling in the scientific process. Some cats did not receive these slips of paper. The researchers then placed the cats—both iridoid-perfumed and not—within reach of many mosquitoes. The mosquitoes bit the faces of the cats who had not received the iridoid-soaked paper. However, the mosquitoes did not bite the faces of the cats who had received the iridoid-soaked paper.

We know what you’re thinking: “Wait, if I rub some catnip on my body, will mosquitoes stay away from me?” And, unfortunately, the researchers don’t recommend that humans use catnip as a natural repellent (although it may help you attract the neighborhood kitties). In fact, researchers don’t even recommend that cats should use catnip as a natural repellent, until there is more evidence.

But, you can use catnip in other ways. Catnip has been cultivated for centuries and used for medicinal purposes. A tonic made from the plant is said to be a good remedy for colds. Catnip is also used as an herbal tea and provides a seasoning for cooking. So, if you can get your hands on some traditional human foods seasoned with catnip, enjoy! You will not have to share with mosquitoes. But, as for your cat, that might be a different story . . .

Giant Cat Found Lounging Among Archaeological Wonders

This month, archaeologists discovered a catlike figure carved into a hillside in Nazca, Peru. Archaeologists are people who study the remains of past human cultures. The cat is the latest geoglyph (ground etching) to be found in a region famous for its giant designs. The Nazca people marked into the ground these designs, also called the Nazca lines. The Nazca were a Native American culture that lived as early as 100 B.C. to A.D. 800 in the coastal desert of what is now southern Peru. Drawn centuries before such other famous cats as Garfield and the Chesire Cat, this catlike geoglyph illustrates the timeless appeal of our feline friends.

The catlike image in Nazca has pointy ears, round eyes, and a striped tail. It is also engaged in a favorite cat pastime—lounging. Its long body stretches 40 yards (37 meters) on the hillside. The geoglyph is said to date from 200 B.C. to 100 B.C.—making it a lot of cat years old. The cat is believed to be older than the other geoglyphs that have been discovered at Nazca over the years. Archaeologists came across the etching while they were remodeling a section of the hill.

The Nazca made the geoglyphs by removing surface stones and piling them along the edges of the designs. Removing the dark rocks exposed the bright sand beneath. The designs have lasted for centuries in the desert environment, with little rain or wind to wear them away. The geoglyphs can only be seen in full from the air.

Many of the geoglyphs form the outlines of gigantic animals and plants. They include figures of a killer whale, a lizard, a monkey, and a spider. More common are geometric forms, including spirals, straight lines, trapezoids, and triangles. Some of the lines appear to spread outward from small hills, like the spokes of a wheel. The lines stretch for miles or kilometers across the desert. Platforms lie near the bases of many of the trapezoids.

In 1994, the United Nations Educational, Scientific and Cultural Organization (UNESCO) declared the Nazca lines a World Heritage Site. UNESCO gives this designation to areas of unique natural or cultural importance.

Scholars believe that the Nazca lines had several functions. Investigations by scientists indicate that people gathered and walked on the lines. Scholars think that people placed offerings on platforms around the shapes to encourage the nature spirits to provide rain for their crops. The animal designs symbolized the essence of the nature spirits, whereas some of the geometric lines led pilgrims to ritual centers.

International Cat Day

Wednesday, August 7th, 2019

August 7, 2019

To people with a cat in the family, every day may seem like “cat day.” But tomorrow, August 8, is officially International Cat Day, a holiday that celebrates felines of all forms and temperaments and encourages people to love, help, and protect the animals. Started by the International Fund for Animal Welfare (IFAW) in 2002, International Cat Day is celebrated in cat-obsessed cultures around the world. IFAW is one of the world’s largest animal welfare and conservation charities.

People celebrate International Cat Day in a wide variety of ways. Sometimes as particular as cats themselves, cat lovers may pamper their pets, donate to animal charities, or flood social media with cat images and videos (more than they do already). Cat parades and parties are organized, people visit cat cafés, and international names are bestowed upon cats for the day. Mister Whiskers and Fluffy become Señor Bigotes and Peluche in Spanish, Simba becomes Lion in the translation from Swahili, and little Lucy gains international flare as Lou-lou, Lucette, Lucia, or Lucinda. However you choose to celebrate the holiday, it is an excuse to take a cat nap with your pet and give the critter a little extra love and attention.

No one knows exactly when the first cats were domesticated, but archaeologists discovered a cat buried alongside a human in a 9,500-year-old grave in Cyprus. According to the Guinness Book of World Records, the earliest known recorded pet cat name was Nedjem (loosely translated as Sweetie or Precious) during the reign of Thutmose III (1479-1425 B.C.). Thutmose was a pharaoh of ancient Egypt, where cats were considered sacred.

Throughout history, people have valued cats for their skill at hunting and killing mice, rats, and snakes. Cats help keep farms, homes, and businesses free of these animals. People in many societies believe cats bring good fortune. The grace and beauty of cats have made them favorite subjects of artists, and cats have been featured in almost every type of literature. They appear in the mythology of ancient Greece and Rome, and Asian writers have praised cats in their stories and poems for many centuries. Cats are also commonly mentioned in the fairy tales, folklore, and legends of many countries. In modern times, cats are commonly featured in books, comic strips, motion pictures, musicals, and television programs.

Cat holidays are not limited to August 8. October 29 is National Cat Day in the United States, and March 1 is World Cat Day in Russia. In Japan, February 22 was chosen as Cat Day because in Japanese, the number 2 (二) is pronounced ni, so the date 2/22 reads as ni ni ni, similar to the way cats “talk” (nyan nyan nyan, or meow meow meow) in that country.

Ancient Egypt’s Cats and Beetles

Monday, May 6th, 2019

May 6, 2019

Late last year, archaeologists in Egypt discovered a treasure trove of statues and mummified remains at a newly opened tomb complex in Saqqarah (also spelled Saqqara), an ancient site near Cairo. Antiquities are commonly found in Egypt, but this discovery was different: it was dedicated almost entirely to cats and scarab beetles. Saqqarah was the necropolis (burial ground) for Memphis, the capital of ancient Egypt for more than 2,000 years.

The recently opened tombs at Saqqarah are about 4,500 years old. Inside, archaeologists found some human remains as well as ceramic amulets and jars of writing utensils. The more interesting finds, however, were the dozens of mummified cats and scarab beetles. Some of the mummified cats may well have been treasured pets of the deceased, but others were probably included solely to please the feline goddess, Bastet. (Bastet was the goddess of cats as well as human fertility, love, and motherhood.) More than 100 gilded wooden cat statues were also in the tombs, along with an impressive bronze statue of Bastet. Animal statues and mummies are commonly found in ancient Egyptians tombs. Some animals were seen as physical manifestations of gods, and they were included in burials for companionship, food, protection, or religious offerings in the afterlife.

The preserved scarab beetles, a rare find, were wrapped in linen inside small decorated limestone sarcophagi (stone coffins). The Egyptians had a scarab beetle (or scarab-headed) deity, Khepri, a solar god of resurrection and immortality. Compared to Bastet, who had her own popular cult, Khepri was relatively obscure. Combined with the difficulty of embalming delicate beetles, that may explain the small numbers of scarab mummies found over the years.

Animal embalming was a vast industry in ancient Egypt. Sadly, this means that many animals—particularly cats and dogs—were captured or raised specifically to be offered as sacrifices for the dead. Millions of mummified animals have been found over the years. In 2015, a Saqqarah catacomb dedicated to the dog or jackal-like god of mummification, Anubis, was found stuffed with nearly 8 million animal mummies—most of them dogs. Such animals as baboons, cobras, crocodiles, falcons, ibises, and mice were also commonly mummified.

Monster Monday: The Mind-Controlling Parasite

Monday, December 14th, 2015

December 14, 2015

Not feeling like yourself lately? It’s probably just a passing sensation. But if you are a mouse, you just might be under the influence of a mind-controlling parasite—Toxoplasma gondii.

A parasite is a creature that lives on or in another living thing, called the host, taking advantage of the host’s resources. T. gondii is a type of single-celled creature called a protozoan. It can live inside the body of a wide variety of warm-blooded animals, but a critical stage in its life cycle is only known to take place in felines. The creepy part is how the parasite spreads from cat to cat.

Cats get T. gondii mainly from eating rodents infected with the parasite. Rodents, such as mice, pick up the parasite from their environment. But T. gondii does not sit idle inside the rodent’s body, waiting for it to be picked off by a prowling feline. Instead, T. gondii somehow alters its host’s behavior. Normal rodents have an instinctive fear of felines—just a whiff of feline scent is generally enough to send a mouse scurrying for safety. But rodents with T. gondii show a decreased aversion to feline smells. This dampening of instinct makes it more likely that the rodent will engage in risky behavior, increasing the odds that it will be eaten by a cat and thus spread the parasite.

So much for the mouse, you might think. But we human beings love our cats—Westerners keep more cats as pets than any other animal. So it may not be too surprising that scientists estimate that one-third to one-half of all people may be chronically infected with T. gondii, which can lead to a disease called toxoplasmosis. Toxoplasmosis is rarely serious in healthy people. But the parasite remains in the body after symptoms pass, and scientists have begun to wonder whether the same mechanism that makes infected rodents fearless could also contribute to reckless behavior among people. One small study intriguingly suggests that people infected with T. gondii are more likely than others to be involved in traffic accidents.
