Luckily I have one cage that is almost exactly the width of one window, so I am able to fit the cage into the bottom to act as a sort of porch for the fuzzies. I also have set up a series of black corrugated tubes, one branch of which leads to the verandah window which is open whenever the temperature is remotely tolerable. They never bother the other screens when the "porch" is in. [Posted in FML issue 2611]
