A “feral” cat is a non-domesticated cat. It can be any color and any breed (Siamese, etc.). A feral cat is not going to want to be around you, get in your lap, or be petted. A “friendly” cat would want to have your attention and might follow you to the house from the barn. Do not worry about a feral cat attacking any child or other person. Once they are released from their relocation cage, they will stay far away and you may not even see them.
