It's Not Easy Potty Training A Cow

Cows poop. No kidding, right? It’s news to me, and probably to a lot of other city slickers out there, though, that they poop between 10 and 15 times a day. Plus, they pee around 10 times a day.

All that waste adds up pretty quickly (and piles up, too, if the cow doesn’t move around a lot), and causes some significant health and environmental problems on dairy farms. Ammonia and nitrogen get released and contribute to air pollution. Standing in their own filth can make the cows sick or give them hoof problems. Dirty, poop-crusted cows also mean that the farmer loses time cleaning them off before each milking. If he doesn’t at least keep the udders clean, then there’s the risk of milk contamination or lower milk quality.

Training the cows to go in a certain spot or at a certain time would go a long way towards controlling all that poop and curbing these problems. And that’s just what three Canadian scientists set out to do in a study published earlier this month. They knew that dairy farmers often had problems cleaning their cows’ feet because as soon as the animals stepped into the footbath, they’d go to the bathroom and contaminate the water. They also knew that some cows kept in barn stalls had been successfully conditioned, with mild electric jolts, to back up before pooping to keep the waste out of the stall. They combined these two ideas and wondered if water could be used as a stimulus to get cows kept in more open housing systems or in pastures to only do their business in specific places.

They ran four different tests with 12 Holstein dairy cows. In the first, the cows walked through either an empty or full footbath while their “eliminative behavior” was dutifully recorded. In the second, the cows stood still in either an empty footbath, a full one, or one with running water. In the third, the cows stood in an empty bath and either had water, air, or nothing sprayed at their feet. The fourth test was a repeat of the first.

Overall, none of the stimuli reliably got the cows to relieve themselves. More cows went in the full footbath (67 percent) than the empty one (42 percent) in the first test, but there was almost no difference between the two when the test was repeated at the end of the experiment. The researchers also noticed that defecation and urination generally decreased in each test as the days wore on. All this leads them to think that the cows pooped not so much because of the water itself but because the novel experience of getting in the footbath was frightening. The trick to getting cows to go on command, then, might be scaring the crap out of them.

This Is the Age When Puppies Reach 'Peak Cuteness'

All puppies are cute, but at some point in a young dog's life, it goes from "It's so cute I could squeeze it to death" to merely regular cute. But when? According to one recent study in the journal Anthrozoös, peak cuteness hits between 6 and 8 weeks old for many dogs, The Washington Post reports.

Finding out when puppies reach their peak attractiveness to humans may give us insights into how domestic dogs evolved. Researchers from the University of Florida asked 51 students at the school to look at 39 black-and-white images of dogs, who belonged to three different breeds and whose ages ranged from birth to 8 months. The viewers then rated them on a sliding scale of squishability.

The results will sound familiar to dog lovers. Puppies aren't entirely adorable immediately after they're born—they can look a little rat-like—and the participants rated them accordingly. As dogs get older, as much as we might love them, their squee-worthy cuteness declines, as the attractiveness scores reflected. The sweet spot, it turns out, is right around when puppies are being weaned, or between 6 and 8 weeks old.

The participants tended to rate dogs as most attractive when the pups were within the first 10 weeks of their lives. According to the results, Cane Corsos were at their cutest around 6.3 weeks old, Jack Russell terriers at 7.7 weeks old, and white shepherds at 8.3 weeks.

The study only used still photos of a few breeds, and it's possible that with a more diverse sample, the time of peak cuteness might vary a bit. Certain puppies might be cuter at an older age, and certain puppies might be cuter when they're even younger. But weaning age happens to coincide with the time when puppies are no longer getting as much support from their mothers, and are thus at a high risk of mortality. By evolving to attract human support at a time when they're most vulnerable, puppies might have boosted their chance at survival until they were old enough to completely take care of themselves.

The Cat Art Show Is Coming Back to Los Angeles in June

After dazzling cat and art lovers alike in 2014 and again in 2016, the Cat Art Show is ready to land in Los Angeles for a third time. The June exhibition, dubbed Cat Art Show 3: The Sequel Returns Again, will feature feline-centric works from such artists as Mark Ryden, Ellen von Unwerth, and Marion Peck.

Like past shows, this one will explore cats through a variety of themes and media. “The enigmatic feline has been a source of artistic inspiration for thousands of years,” the show's creator and curator Susan Michals said in a press release. “One moment they can be a best friend, the next, an antagonist. They are the perfect subject matter, and works of art, all by themselves.”

While some artists have chosen straightforward interpretations of the starring subject, others are using cats as a springboard into topics like gender, politics, and social media. The sculpture, paintings, and photographs on display will be available to purchase, with prices ranging from $300 to $150,000.

Over 9000 visitors are expected to stop into the Think Tank Gallery in Los Angeles during the show's run from June 14 to June 24. Tickets to the show normally cost $5, with a portion of the proceeds benefiting a cat charity, and admission will be free for everyone on Wednesday, June 20. Check out a few of the works below.
