Why Are Cats Afraid of Water?

Cats are composed animals, rarely given to emotional outbursts. Get a cat wet, however, and you are likely to witness a total abandonment of any semblance of composure, with the feline going from docile to a windmill of claws, teeth, and flying fur.

According to John Bradshaw, Ph.D., the Foundation Director of the Anthrozoology Institute at the University of Bristol and the author of Cat Sense, there’s more to the phobia than just matted fur: Cats may have an ancestral fear of getting wet. “Domestic cats were descended from Arabian wild cats,” he says. “Their ancestors lived in an area with very few large bodies of water. They never had to learn how to swim. There was no advantage to it.”

A cat’s displeasure extends to the physical sensation of being doused. According to Shaw, an oily coat doesn’t shed water easily, making it hard for them to return to a dry, warm state quickly. Cats are also used to feeling nimble—in water, their motions become sluggish.

Not all species of cat avoid swimming, however. The van cats that live near the shore of Lake Van in Eastern Turkey are reared to dive in as kittens, with their mothers nudging them in. There’s also the paradoxical behavior of many cats who look at trickling faucets with what appears to be awe. Some dip a paw in the stream; others begin to drink from it.

But it’s not really the water that the cat is interested in. “That flickering pattern, the light coming off the water, is hard-wired into their brain as a potential sign of prey,” Bradshaw says. “It’s not because it’s wet. It’s because it moves and makes interesting noises. Something moving is a potential thing to eat.” As far as cats are concerned, a little water goes a long way.

What's the Difference Between Memorial Day and Veterans Day?

It may not be easy for some people to admit, but certain national holidays often get a little muddled—namely, Memorial Day and Veterans Day. In fact, the U.S. Department of Veterans Affairs sees the confusion often enough that they spelled out the distinction on their website. The two days are held six months apart: Veterans Day is celebrated every November 11, and Memorial Day takes place on the last Monday of May as part of a three-day weekend with parades and plenty of retail sales promotions. You probably realize both are intended to acknowledge the contributions of those who have served in the United States military, but you may not recall the important distinction between the two. So what's the difference?

Veterans Day was originally known as Armistice Day. It was first observed on November 11, 1919, the one-year anniversary of the end of World War I. Congress passed a resolution making it an annual observance in 1926. It became a national holiday in 1938. In 1954, President Dwight D. Eisenhower changed the name from Armistice Day to Veterans Day to recognize veterans of the two world wars. The intention is to celebrate all military veterans, living or dead, who have served the country, with an emphasis on thanking those in our lives who have spent time in uniform.

We also celebrate military veterans on Memorial Day, but the mood is more somber. The occasion is reserved for those who died while serving their country. The day was first observed in the wake of the Civil War, where local communities organized tributes around the gravesites of fallen soldiers. The observation was originally called Decoration Day because the graves were adorned with flowers. It was held May 30 because that date wasn't the anniversary for any battle in particular and all soldiers could be honored. (The date was recognized by northern states, with southern states choosing different days.) After World War I, the day shifted from remembering the fallen in the Civil War to those who had perished in all of America's conflicts. It gradually became known as Memorial Day and was declared a federal holiday and moved to the last Monday in May to organize a three-day weekend beginning in 1971.

The easiest way to think of the two holidays is to consider Veterans Day a time to shake the hand of a veteran who stood up for our freedoms. Memorial Day is a time to remember and honor those who are no longer around to receive your gratitude personally.

What Is the Kitchen Like on the International Space Station?

Clayton C. Anderson:

The International Space Station (ISS) does not really have a "kitchen" as many of us here on Earth might relate to. But, there is an area called the "galley" which serves the purpose of allowing for food preparation and consumption. I believe the term "galley" comes from the military, and it was used specifically in the space shuttle program. I guess it carried over to the ISS.

The Russian segment had the ONLY galley when I flew in 2007. There was a table for three, and the galley consisted of a water system—allowing us to hydrate our food packages (as needed) with warm (tepid) or hot (extremely) water—and a food warmer. The food warmer designed by the Russians was strictly used for their cans of food (about the size of a can of cat food in America). The U.S. developed a second food warmer (shaped like a briefcase) that we could use to heat the more "flexibly packaged" foodstuffs (packets) sent from America.

Later in the ISS lifetime, a second galley area was provided in the U.S. segment. It is positioned in Node 1 (Unity) and a table is also available there for the astronauts' dining pleasures. Apparently, it was added because of the increasing crew size experienced these days (6), to have more options. During my brief visit to ISS in 2010 (12 days or so) as a Discovery crewmember, I found the mealtimes to be much more segregated than when I spent five months on board. The Russians ate in the Russian segment. The shuttle astronauts ate in the shuttle. The U.S. ISS astronauts ate in Node 1, but often at totally different times. While we did have a combined dinner in Node 1 during STS-131 (with the Expedition 23 crew), this is one of the perceived negatives of the "multiple-galley" scenario. My long duration stint on ISS was highlighted by the fact that Fyodor Yurchikhin, Oleg Kotov, and I had every single meal together. The fellowship we—or at least I—experienced during those meals is something I will never, ever forget. We laughed, we argued, we celebrated, we mourned …, all around our zero-gravity "dinner table." Awesome stuff!
