A feral cat is a domestic cat that has reverted to a wild state, typically living outdoors without human care. These cats are often born in the wild or abandoned by their owners, and they tend to form colonies where they can find food and shelter. Unlike house cats, feral cats are usually wary of humans and may avoid contact. Feral cats play a significant role in controlling rodent populations, but they can also pose challenges to local wildlife. Many communities implement trap-neuter-return (TNR) programs to manage feral cat populations humanely, allowing them to live out their lives without contributing to overpopulation.
