All I could think when I saw this story was “I hope it never bites her” ... she may not have a “spotted” hyena, but I would think all hyenas are going to be fairly close in bite strength:

The Spotted Hyena (Crocuta crocuta) is a scavenging carnivorous African mammal. It has one of the strongest bite strengths of any mammal due to its strong jaws.
A dog, for example, such as a Mastiff or Rottweiler, has an average bite strength of 325 pounds per square inch. An African Lion has a bite strength of 650 pounds per square inch. A Bengal Tiger has a bite strength of 1,050 pounds per square inch. The Spotted Hyena has a bite strength of 1,100 pounds per square inch.
A Great White Shark has an average bite strength of 625 pounds per square inch. A Hippopotamus has an average bite strength of 1,825 pounds per square inch. The animal with the strongest bite strength is the crocodile at 3,700 pounds per square inch.
They do have some pretty nasty bone crunchers.
Bet she only gets her mail once a month, if that.
They supposedly estimate captive orca bite strength at around 19,000lbs per square inch.
