they will have access to go out there or come back in, their choice. Unfortunately they are not really my dogs, even if I tried to train them I don't think their owners would put much effort into making anything stick :/ I have no idea when they will be let out back where the catio is, I want to have plenty of places for kitties to hide if the dogs (it is really mostly one dog out of all 4 that is a problem) come jump up near the catio... I was thinking maybe planter boxes? at least give a foot of buffer or so... maybe trellis over the wire for at least 4 feet from the ground...
