The relationship between man and animal predates capitalism, but that hasn't stopped some of the wealthiest people to ever live from trying to mix the two by leaving their ridiculous fortunes to their pets. Which means that there are cats and dogs on this planet who have more money than you could ever hope to accumulate in your lifetime.

Some of the richest animals in the world have made their money through inheritance, but others have made it through marketing or acting. Here are 10 of the richest animals in the history of the world

1. GUNTHER IV

Gunther IV is a second generation ​millionaire canine—and currently the richest animal in the world. His father, Gunther III, inherited $80 million from German Countess Karlotta Liebenstein. He, in turn, left that money to his son, whose caretakers have invested his fortune to the point where Gunther IV is worth approximately $400 million. He owns mansions around the world, eats caviar daily, and has his own personal maid.

2. GRUMPY CAT

Grumpy Cat—real name Tardar Sauce—is arguably the most famous animal on the planet, thanks to one of the most enduring internet memes ever created based purely on her permanently disgruntled look. Apart from her social media and merchandising empires, she also starred in her own movie, Grumpy Cat's Worst Christmas Ever, where she was voiced by Aubrey Plaza. Though her net worth is often cited as being about $100 million, her owner said that's not quite true. Still, it's definitely in the millions—and a heck of a lot more than the typical American can ever hope to make.

3. OLIVIA BENSON

She may be owned by Taylor Swift and share a name with a Law and Order: SVU character, but Olivia Benson doesn't just sit back and let the money flow in through her songstress benefactor. She has a huge social media presence and has starred in ads for Coke and Keds Shoes, netting her a personal fortune worth about $97 million.

4. OPRAH WINFREY'S DOGS

Luke, Layla, Sadie, Sunny, and Lauren have the distinction of being the dogs of Oprah Winfrey. That alone would make them rich in spirit, but it has the added hook of an assured inheritance. Winfrey has already agreed to leave the five dogs $30 million upon her death.

5. GIGOO

Gigoo, the chicken formerly belonging to the late British publisher Miles Blackwell, sits on a nest egg of $15 million. Blackwell sold his business and retired to the country just three weeks before he died, meaning that he was basically a middleman between Gigoo and his own net worth.

6. TOMMASINO

Maria Assunta was an extremely wealthy Italian woman who, upon her death, left her $13 million fortune to her cat Tommasino. The wealth wasn't just in cash though; the cat also became the owner of several castles, villas, and estates throughout Italy.

7. BLACKIE

Blackie was once at the top of this list as he used to be the world's wealthiest cat (as confirmed by Guinness World Records). His $12.5 million fortune came purely from inheritance. He is the last surviving pet of Ben Rea, a multimillionaire who was estranged enough from his own family to bequeath his riches to a feline.

8. CONCHITA

When you can afford to buy your dog Tiffany's necklaces and cashmere sweaters, it might be the universe's way of telling you you have too much money. Regardless, deceased heiress and socialite Gail Posner left her Chihuahua Conchita a sizable fortune of $8.4 million—including a posh waterfront pad in Miami—for seemingly no other reason than because she could.

9. BOO

Boo, a famously adorable Pomeranian owned by Irene Ahn, has built a merchandising brand around himself based purely on his unfiltered cuteness. Life-sized stuffed versions of himself are available for purchase, he has his own book, and he has accrued several million social media followers. His net worth currently sits at about $8 million.

10. BART THE BEAR II

Bart the Bear II is one of the few animals on this list to have actually earned his wealth. Basically, if you've seen a bear in a movie in the last 20 years, there's a solid chance it was Bart, who was named after Bart the Bear—an Alaskan Kodiak bear who starred in dozens of projects between the late 1970s and the late 1990s. (Bart passed away in 2000.) Though Bart the Bear II has no biological relation to the original Bart, both are trained by Doug Seus. If Bart II looks familiar, you may have seen him in an episode of Game of Thrones, where he squared off against Brienne of Tarth and Jaime Lannister. He has a net worth of around $6 million.

Keep Your Cat Busy With a Board Game That Doubles as a Scratch Pad

No matter how much you love playing with your cat, waving a feather toy in front of its face can get monotonous after a while (for the both of you). To shake up playtime, the Cheerble three-in-one board game looks to provide your feline housemate with hours of hands-free entertainment.

Cheerble's board game, which is currently raising money on Kickstarter, is designed to keep even the most restless cats stimulated. The first component of the game is the electronic Cheerble ball, which rolls on its own when your cat touches it with their paw or nose—no remote control required. And on days when your cat is especially energetic, you can adjust the ball's settings to roll and bounce in a way that matches their stamina.

The Cheerble balls are meant to pair with the Cheerble game board, which consists of a box that has plenty of room for balls to roll around. The board is also covered on one side with a platform that has holes big enough for your cat to fit their paws through, so they can hunt the balls like a game of Whack-a-Mole. And if your cat ever loses interest in chasing the ball, the board also includes a built-in scratch pad and fluffy wand toy to slap around. A simplified version of the board game includes the scratch pad without the wand or hole maze, so you can tailor your purchase for your cat's interests.

Since launching its campaign on Kickstarter on April 23, Cheerble has raised over $128,000, already blowing past its initial goal of $6416. You can back the Kickstarter today to claim a Cheerble product, with $32 getting you a ball and $58 getting you the board game. You can make your pledge here, with shipping estimated for July 2020.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
