The feral cat is a cat that has been born into wildness or has not had human interaction for a significant period of time and is self-sufficient. There is some disagreement over exactly what classifies a cat as feral, but groups tend to use factors such as the cat's levels of socialization and comfort with humans, and whether it is owned, kept confined, or dependent on humans for survival to determine whether a cat is feral. Feral cats are usually considered to be distinct from stray cats, which are socialized cats who no longer live in homes, but could potentially be reintroduced successfully.
