Animals are not garage or yard sale items.  They are living, breathing, innocent creatures that deserve a chance at a great life.  By allowing non-registered backyard breeders to advertise the illegal sale of their un-altered animals on your site, you are promoting illegal activity and pet overpopulation. About 2.4 million healthy, adoptable cats and dogs—about one every 13 seconds—are put down in U.S. shelters.  Cat and dog breeders are required to be permitted by Collier County Domestic Animal Services to ensure the protection of the animals and the consumer.

By eliminating advertising venues for these illegal activities it may cut down on breeding.  If they don't have a place to sell their animals, they may just stop.  Please be part of the solution and join us by asking your local online yard sale sites to please ban the sale of animals on their page.
