Feral cats are the "wild" offspring of domestic cats and are primarily the result of pet owners' abandonment or failure to spay and neuter their animals, allowing them to breed uncontrolled. Feral cat "colonies" can be found behind shopping areas or businesses, in alleys, parks, abandoned buildings, and rural areas. They are elusive and do not trust humans.
Many people assume their animals will survive when they move away and leave them behind. Contrary to popular belief, domestic animals do not automatically return to their "natural" instincts and cannot fend for themselves!
