Title: Just What I Needed
Review: I bought this to expand my Cat's PetSafe Fence from my yard to include my neighbors yard directly behind me. Our cats enjoy playing together and thought my Stripes did so well learning the new fence, that I thought it was time to reward him with a little extra room to rome... but not too far. However, the flags are useless with him. They mean nothing, but that could have been my persolnal lack of faith in a cat using flags for warning zone boundaries. He sure knows what that beep means though!
