The dealer may receive hundreds of dollars for each animal. Using sedatives hidden in meat, females in heat, and nets, they lure or trap dogs and cats. Newspaper giveaway ads are another source. Bunchers typically clear out entire neighborhoods, then transport the animals several states away to avoid detection, although some animals are sold locally. Animals are also stolen during house burglaries, as well as from cars, sidewalks, and shopping areas.
Some dealers make their living exclusively by selling animals for dissection.
A PETA undercover investigation revealed that the largest suppliers of animals for dissection depend on Class B dealers to stock their catalogues. His cousin, Al Wise, operated a similar cattery and sold cats to Carolina Biological Supply Company. Despite claims from these facilities that they only dealt in animals who had been euthanized at local pounds, undercover videotape showed that deliveries of live cats, many wearing collars, were common. Upon arrival, the animals were shoved into gas chambers and then hooked up to embalming machines. The cats would visibly struggle as formaldehyde was injected into their bloodstreams.
