Where do animals for dissection come from?
Frogs and other small animals area often bred by animal supply houses. Frogs are also captured in the wild, which causes serious environmental problems. In Bangladesh, the mass exportation of frogs for food and experiments has resulted in an overpopulation of crop-damaging insects that the frogs once controlled. Cats and dogs can be taken from pounds and shelters, or rounded up or trapped by dealers and bunchers (see pet theft section).
