Do Pets Enjoy Dressing Up for Halloween?

Each Halloween, social media becomes congested with pictures of people's furry companions decked out in capes, caps, wings, and other Halloween flair. A Labradoodle is adorable to begin with. Put him in a bee costume and people melt.

But look closely at some of these photos. In the pet’s eyes you might see a note of humiliation or sadness. Like the court jester, they’ve been made to be comic relief. Shame seems to envelop them like a dark cloud. It’s as if a dog knows his dignity is circling the drain.

In forcing them to wear a Yoda costume, are we depriving our pets of a basic right to decency? What if they’re just doing it for us?

“That's one possibility,” says Alexandra Horowitz, Ph.D., an adjunct associate professor at Barnard College and author of Inside of a Dog: What Dogs See, Smell, and Know. “We are a society that asks dogs to stay frozen while we balance a dog treat on their nose. It pays off for them because we eventually give them the treat, the attention, the love. Dogs certainly have learned to endure small discomforts for our pleasure.”

Rather than be happy about having an alter ego—say, a hot dog—pets might instead be thinking their human handlers are scolding them, Horowitz says. That's because domesticated dogs have wolf-like ancestors. Their cousins, wolves (Canis lupus), are prone to covering a subservient wolf’s body with their own as a form of reprimand. In covering a dog’s body with a costume, a dog might have a genetic disposition to feel like they’re being corrected. That’s why some might simply freeze in place or otherwise act sullen.

“If they duck to get away, keep their tail low or ears back, or generally keep their body tight and low, that's submissive, appeasement behavior,” Horowitz says.

Even if you feel like you’re not causing your dog emotional damage, costumes should still be evaluated for possible physical dangers. No puppy duds should obscure their eyes or face or fit too snugly around their chest. (It can restrict breathing.) They should be visible in low-light conditions, either for trick-or-treating or in case they dash out of the house. Some vets have reported having to surgically remove small accessories or objects that were dislodged from costumes and swallowed, so it’s good to make sure nothing on the outfit is removable.

If your dog exhibits signs of duress—pawing, itching, cowering, pinned ears, tucked tail—then you should reconsider their participation in the festivities. If you want to test their temperament before buying a costume, try putting them in a T-shirt. If they look unhappy, spare them the additional stress of dressing them up like a taco.

As for cats? “I would not do this,” Horowitz says. “Cats don't suffer our ridiculousness.”

What's the Difference Between Mold and Mildew?

We’re all familiar with colorful spots of something growing in our showers and in other dark, damp areas in our homes, but you may not know what to call it. Is it mold, or is it mildew? What is the difference between the two, anyway?

Both terms refer to fungus, but as it happens, it’s a squares-versus-rectangles situation. Mildew is a type of mold. The term typically describes fungi that grows flat, on surfaces like the walls of your shower or window sills. There are also several types of mildew that are specific to plants—powdery mildew and downy mildew are parasites that grow on certain trees, flowers, and crops, for example. While mold might be a colorful green or black, mildew is typically white.

The word mildew originally came from honeydew, a term for sticky secretions aphids and other insects leave on plants, which people used to think came from the sky, like dew. Eventually, the word came to refer to the mold caused by the fungi that fed on these secretions.

Most of the household growths we refer to as mold belong to just a few families of fungi species. According to the CDC, the most common indoor molds are Cladosporium, Penicillium, Aspergillus, and Alternaria. Household molds can be a variety of colors, from orange-brown to green to gray to black. (Note that not all mold that is black in color is the more toxic species we call “black mold,” or Stachybotrys.) In contrast to the powdery texture of mildew, molds are typically fuzzy or slimy.

In nature, mold can play an important role in the ecosystem, breaking down dead plants and leaves. In your house, those decomposition abilities aren’t quite so welcome. Mold spores fly through the air, and when they land in moist places, they start to grow—whether that’s on food, your ceiling, paper products, wood, carpet, leather, or elsewhere around your house—and in the process, destroy whatever they're growing on. Unlike mildew, most molds grow down into the surface of its habitat, making them more difficult to remove. In porous materials, mold grows into all the empty crevices, which is why it is often impossible to remove all the mold from ceiling tiles (or soft foods like bread).

Getting rid of the unsightly growth in your damp bathroom is more than just a matter of aesthetics. Indoor mold can cause allergic reactions, such as a stuffy nose or itchy eyes, and can lead to infections for people with compromised immune systems. Some people are more sensitive to mold than others, and may experience more symptoms when exposed to it. Generally speaking, though, mold spores are everywhere, so you’re never going to live a totally mold-free life. Spores will come into your home through windows, doorways, ventilation and climate control systems, and via your clothing, shoes, and pets.

But there’s only one way to effectively inhibit mold growth at home: Get rid of the moisture. That means fixing leaks, getting better ventilation, and possibly running a dehumidifier, according to the CDC’s recommendations on mold.

What Happens to Films Selected for Preservation by the Library of Congress?

On Wednesday morning, the Library of Congress announced its latest slate of movies selected for permanent safekeeping in the National Film Registry. As always, the picks varied widely. The National Film Registry’s class of 2018 includes Cinderella (1950), My Fair Lady (1964), Jurassic Park (1993), The Shining (1980), Smoke Signals (1998), and the animated short Hair Piece: A Film for Nappy-Headed People (1984), which was produced by Ayoka Chenzira, one of the first black female animators.

Originally established in 1988, the National Film Preservation Act tasks the board with selecting American films that are “culturally, historically, or aesthetically" significant. They can pick up to 25 per year, and the movies must be at least 10 years old. The National Film Preservation Board is made up of representatives from a number of industry organizations, including the Academy of Motion Picture Arts and Sciences, the Directors Guild of America, and the National Society of Film Critics. With the new selections, there are 750 films in the registry.

Selection for the registry is an honor, of course, but what does it mean beyond that? How does the Library of Congress, the U.S. legislature’s storage agency for documents and media, go about preserving movies?

According to Steve Leggett, program coordinator for the National Film Preservation Board, selection implores the Library of Congress to get the best possible copy of the film in its original format and store it in their vaults at the National Audio-Visual Conservation Center in Culpeper, Virginia. This ensures the film will be available to future generations.

For Hollywood movies, the process is usually pretty easy. “We simply ask the studio to donate a copy,” Leggett told Mental Floss in 2015. In some cases, that isn’t even necessary. The Library of Congress has more than 1 million films on file, many of them sent by studios or filmmakers for the sake of copyright registry. When the original Star Wars was selected in 1989, Leggett says, congressional librarians simply checked that the 35 millimeter print submitted with Lucasfilm’s copyright application was in good shape. It was, so no further action was needed.

For older and more esoteric selections like newsreels, silent films, documentaries, and early technical achievements in filmmaking, Leggett says the library often seeks out a copy from the community of preservationists. Universities, private foundations, and hobbyists that preserve old films might get a call from the Library of Congress if they have a good copy of a National Film Registry selection. In rare cases, the library will barter for the film, using redundant materials on its shelves. Other times, it will make a copy or pay the archivist to make a new 35 millimeter copy for them. The Culpeper facility stores nitrate prints, the original film stock for many early movies, in specialty lockers because the material is highly volatile and flammable.

Silent films can be tricky because studios often released, revised, and then re-released versions of the film. When one is selected, Library of Congress archivists collect as many aspects and versions of the film as they can, which might mean contacting several studios and archivists.

Of particular challenge in 2015 was the induction of Symbiopsychotaxiplasm: Take One, William Greaves’s quasi-documentary of his 1968 theatrical project staged in Central Park. The film was screened often through the years, as Greaves gained a cult following. It was released on DVD in 2006, but the National Film Preservation Act specified that the library should seek a copy in the original format, which it didn’t have. Leggett said Greaves’s 1968 original cut was “lost,” but the library worked with the late filmmaker's estate to create a new 35 millimeter version that resembled it.

The Audio-Visual Conservation Center itself, buried on a mountainside, has storage space controlled to stay cool and dry. “A film could survive for hundreds of years there,” Leggett says. He admits the audiovisual center wouldn’t survive a nuclear strike—in the event of World War III, the world might lose its best copy of Buster Keaton’s The General—“but it did survive an earthquake with all materials intact.”
