Even with training and domestication, pets have been known to turn on their owners. Sadly, this is all the more common with exotic animals that are difficult or impossible to train, such as lions, bears, and snakes. These stories are tragic, usually of devoted guardians attempting to simply do what can't be done - tame a wild beast.
Pets who have turned on their humans include a famous chimpanzee, various reptiles, a hippo that inspired a TV special, bears, and even spiders. Some of these cases are the result of obvious bad ideas, but many were just animal owners who had fallen in love with an exotic creature and paid the ultimate price.
Travis the Chimpanzee became famous after he appeared on TV with his owner Sandra Herold. In 2009, Herold called her friend Charla Nash for help getting the 200-pound chimp back into his cage.
But when Travis saw Nash, he attacked. Herold tried to stop Travis with a knife, which only angered him more. She called 911 and police arrived, which led to Travis ripping off the door of one of the police cars. An officer shot Travis, ending the chimp's rampage.
Nash eventually received a settlement from Herold's estate and has undergone extensive reconstructive surgery.
A Florida woman and her family were accosted by her pet pitbull after she tried to make him wear a sweater.
The pitbull named Scarface went after Brenda Guerrero, 52, in her Tampa home on New Year's Day in 2017. When her husband Ismael stepped in to help her, the dog turned on him. The couple's 22-year-old son tried to intervene but failed to stop the dog.
The three eventually managed to escape, leaving the dog outside. Animal Control officers were called to the home and had to subdue the dog with a Taser. Officials said Scarface was "pretty aggressive." Sounds like an understatement.
The Walz family of Allentown, PA, had raised their 350-pound black bear Teddy since it was a cub. But even so, the bear attacked and killed Kelly Ann Walz as she was cleaning his cage. She made the mistake of cleaning the cage while Teddy was still in it, which apparently set him off. Neighbor children saw the incident, and their father shot Teddy.
Authorities soon discovered that Kelly's husband's license to keep and sell exotic animals had expired.
A resident of Dortmund, Germany, Mark Voegel lived a solitary life in a small apartment, keeping the company only of the numerous insects and snakes he collected as pets. It was one of these, a black widow spider, that caused his demise. In the roughly two weeks it took for him to be found, his menagerie feasted on him.
Hundreds of spiders, lizards, and snakes - along with countless termites - had consumed him, with webs draping his body, and bits of him scattered all around the apartment.
