A jaguar named Macho B. may have been the only wild jaguar left in the United States. He's been photographed near the Mexican border in Arizona since 1996. He was caught and released on February 18th, when wildlife officials fitted him with a tracking device. In the past few days, a biologist tracking Macho B. noticed his lethargic behavior, so Arizona Game and Fish officers recaptured him. They found the jaguar to be suffering from severe kidney failure, and he was euthanized. Macho B. was estimated to be 14-16 years old. Link

At least the jaguar was lucky enough to be euthanized and not have to suffer the slow agonizing toxic death of renal failure.
The only time I see badgers, raccoons, and porcupines (which are extremly rare where I live) is when they have been hit by a car.
