A definition of a feral at is "having escaped from domestication and become wild." Feral cats come from either two sources, they are either the offspring of socialized cats or they are just unsocialized cats. While many have been feral all of their lives, their origins were primarily from cats who had been kept as companions. Some estimates place the number of these animals in the United States at approximately 60 million cats.
I have a soft spot for ferals and have been rescuing them now for over 12 years. As Debra has said, there is nothing like having a feral and watching a cat who basically has learned to trust no one, come to trust and appreciate me and give me so much pleasure along the way.
