During the Stripper/Drug mule arc Brad was tasked by the strippers creepy uncle to get rid of a cat that had been living at the house. Brad claims he was driving to a shelter to give the cat up when he was distracted by the cat in his car and drove into (not sure if it was the back of another car or a concrete pole) concrete pole writing the car off and allowing the cat to escape to "freedom".
(More Information Needed: What was the cats name? Which car was Bradley Driving? How long had Bradley known the cat? Did Bradley like the cat? Why were they getting rid of the cat?)
