The FDA has recalled several brands of dry dog food that contain potentially toxic levels of vitamin D, The Atlanta Journal-Constitution reports. While vitamin D is essential for dogs, too much of the nutrient can result in kidney failure and other serious health problems.

The FDA has already received reports of vitamin D toxicity in dogs that consumed certain dry foods. Pet owners are advised to stop using the following products:

Old Glory Hearty Turkey and Cheese Flavor Dog Food (manufactured by Sunshine Mills, Inc.)

Evolve Chicken & Rice Puppy Dry Dog Food (Sunshine Mills, Inc.)

Sportsman's Pride Large Breed Puppy Dry Dog Food (Sunshine Mills, Inc.)

Triumph Chicken & Rice Recipe Dry Dog Food (Sunshine Mills, Inc.)

ELM K9 Naturals Chicken Recipe (ELM Pet Foods, Inc.)

ANF Lamb and Rice Dry Dog Food (ANF, Inc.)

Symptoms of vitamin D poisoning usually develop 12 to 36 hours after pets consume a suspect food, according to PetMD. The FDA says those symptoms include vomiting, loss of appetite, increased thirst, increased urination, excessive drooling, and weight loss. "Customers with dogs who have consumed this product and are exhibiting these symptoms should contact their veterinarian as soon as possible," the FDA writes.

The agency says the situation is still developing, and it will update the list of recalled brands as more information becomes available. According to WKRN News, veterinary professionals recommend sticking to dog foods that have an AAFCO label (from the Association of American Feed Control Officials) on them.

No Venom, No Problem: This Spider Uses a Slingshot to Catch Prey

There are thousands of ways nature can kill, and spider species often come up with the most creative methods of execution. Hyptiotes cavatus, otherwise known as the triangle weaver spider, is one such example. Lacking venom, the spider manages to weaponize its silk, using it to hurl itself forward like a terrifying slingshot to trap its prey.

This unusual method was studied up close for a recent paper published in the Proceedings of the National Academy of Sciences by researchers at the University of Akron in Ohio. They say it's the only known instance of an animal using an external device—its web—for power amplification.

Hyptiotes cavatus's technique is simple. After constructing a web, the spider takes one of the main strands and breaks it in half, pulling it taut by moving backwards. Then, it anchors itself to a spot with more webbing in the rear. When the spider releases that webbing, it surges forward, propelled by the sudden release of stored energy. In the slingshot analogy, the webbing is the strap and the spider is the projectile.

This jerking motion causes the web to oscillate, tangling the spider's prey further in silk. The spider can repeat this until the web has completely immobilized its prey, a low-risk entrapment that doesn’t require the spider to get too close and risk injury from larger victims.

The triangle weaver spider doesn’t have venom, and it needs to be proactive in attacking and stifling prey. Once a potential meal lands in its web, it’s able to clear distances much more quickly using this slingshot technique than if it crawled over. In the lab, scientists clocked the spider’s acceleration at 2535 feet per second squared.

Spiders are notoriously nimble and devious. Cebrennus rechenbergi, or the flic-flac spider, can do cartwheels to spin out of danger; Myrmarachne resemble ants and even wiggle their front legs like ant antennae. It helps them avoid predators, but if they see a meal, they’ll drop the act and pounce. With H. cavatus, it now appears they’re learning to use tools, too.

Plano, Texas Is Home to a Dog-Friendly Movie Theater That Serves Bottomless Wine or Whiskey

K9 Cinemas
K9 Cinemas

For dog owners in Plano, Texas, movie night with Fido no longer just means cuddling on the couch and browsing Netflix. The recently opened K9 Cinemas invites moviegoers—both human and canine—to watch classic films on the big screen. And the best part for the human members of this couple? Your $15 ticket includes bottomless wine or whiskey (or soft drinks if you're under 21).

The theater operates as a pop-up (or perhaps pup-up?) in a private event space near Custer Road and 15th Street in Plano. Snacks—both the pet and people kind—are available for $2 apiece. Dogs are limited to two per person, and just 25 human seats are sold per showing to leave room for the furry guests.

Pet owners are asked follow a few rules in order to take advantage of what the theater has to offer. Dogs must be up-to-date on all their shots, and owners can submit veterinary records online or bring a hard copy to the theater to verify their pooch's health status. Once inside, owners are responsible for taking their dog out for potty breaks and cleaning up after any accidents that happen (thankfully the floors are concrete and easy to wipe down).

While many of the movies shown are canine-themed—a recent screening of A Dog's Journey included branded bandanas with every ticket purchase—they also hold special events, like a Game of Thrones finale watch party (no word on how the puppers in attendance responded to Jon Snow finally acknowledging what a good boy Ghost is).
