Definitions from Hawaiʻi 

Defines feral as “having escaped or been released from domestication and reverted to a wild state.”

"Feral cats are identical to the common pet cat and are the same species separated only by lifestyle and behavior. Feral cats may utilize human resources or live completely independently and can be found in all types of habitat, including free-ranging in the mauka lands."

"A stray cat is a pet who has been lost or abandoned, is used to contact with people and is tame enough to be adopted. A feral cat is the offspring of stray or other feral cats and is not accustomed to human contact."
