Thread: Outdoor /Indoor

Thanks for that antonia - didnt know that one - knew you could get collars but she cant wear one. I will have to investigate that

The problem with all the catflaps I know of, microchip or collar keyed, is that the permissioned opening only works in one direction. You cannot stop all but one cat going out - but someone must have thought of this problem before.

You could build an "airlock" if you have a utility room or something, with two catflaps, both opening freely from the airlock but only allowing chosen moggie into the airlock from either side. Expensive though.
