The worldwide decline of many wild cat populations is becoming increasingly evident. This decline may be attributed to several factors: (1) the fur trade; (2) the pet trade; (3) habitat destruction; (4) predator control programs; and (5) trophy hunting activities. Legislation in the form of the Endangered Species Conservation Act has moved to counteract such population decreases through partial restriction of wild felid importation.
