Do Racehorses Really Pee All That Much?

We’ve all heard the phrase “pee like a racehorse,” but are the animals' urinary habits all they’re cracked up to be? Do horses really pee a startling amount?

Oh yeah. Penn State University’s College of Agricultural Sciences pegs a horse’s daily urinary output at around 0.3 fluid ounce per pound of body weight, or about two and half gallons for a typical 1000-pound horse. According to Al Cirelli Jr., an equine specialist at the University of Nevada, the amount of urine produced can even jump up to eight gallons per day, depending on the animal’s size, diet, activity levels and environmental conditions. 

Horses can sometimes get some assistance from the veterinarian when it comes to making water, too. Racehorses are prone to “exercise induced pulmonary hemorrhages,” or blood in their airways brought on by the intense physical effort of racing. Horses that are “bleeders” are often given a medication called furosemide to reduce or prevent hemorrhaging. The drug prevents their blood pressure from getting too high and reduces swelling and fluid retention by getting rid of water in the form even more pee.

'Angry Badger' Terrorizes Scottish Castle, Forcing Closures

Portions of the 16th-century Craignethan Castle in Scotland were shut down last week after a less-than-friendly badger holed up there and refused to leave. Historic Environment Scotland, which manages the site in South Lanarkshire, sent out a tweet last Friday notifying visitors that the property's cellar tunnel would remain closed over the weekend “due to the presence of a very angry badger.” Staff tried to coax it out with cat food and honey, but the badger did what it wanted, and they were unable to move the mammal.

A spokesman for HES told the BBC, "The castle is surrounded by woodland and we believe the badger may have become lost. Staff first spotted some dug-out earth on Wednesday evening, and later spotted the badger on closer inspection."

On Saturday, staff used a GoPro camera to check out the tunnel from a safe distance and learned that the badger had left voluntarily, but not before making a mess. The critter dug through both soil and stonework, according to The Scotsman. The castle, an artillery fortification erected around 1530, is already partly in ruins.

Badgers are not typically dangerous, but they can become aggressive if they feel cornered or threatened. They can be seen year-round in Scotland, especially during spring and summer. Earthworms, bird eggs, small mammals, fruit, and roots are among their favorite meals, and they can even be “tempted into your garden by leaving peanuts out—a tasty snack for our striped friends,” the Scottish Wildlife Trust says.

Big Questions
Why Do Cats Sleep So Much?

Cats can sleep 16 to 20 hours a day. It’s not always deep sleep. Cats spend a lot of time taking short “cat naps” that build their energy, yet keep them alert enough to jump up the moment they sense danger or excitement. They don't sleep a lot because they’re lazy or bored. Cats sleep so that they’re ready to hunt.

Their genes (geenz) tell them to. Genes are the tiny instructions inside the cells of all living things that make a species look and act certain ways. These instructions get passed down from parents to kids. In the case of cats, their genes tell them to sleep a lot, especially during the day. 

A long time ago, cats weren’t domesticated (Doh-MESS-tih-cay-ted). That means they were wild and didn't live with humans. Cats had to hunt to survive, and they needed a lot of energy for that. Just like lions, tigers, and other wild cats, domesticated cats sleep more during the day so they’ll be ready to hunt at night, especially around sunrise and sunset. Of course, most house cats no longer have to hunt at all. But just in case they do, their genes tell them to nap often so they’ll be ready.

Cats can sleep in some pretty strange places, as you can see in this video
