A great idea that I’ve considered a time or two, but (at least in this part of Kahlifoania) without really fine netting present, fleas would be all over mah babiez.
I had an outdoor cat that refused to come indoors and every month I put Revolution on her. Whenever I combed her I couldn’t pull off a flea, tick, or any blood residue. It also covers mange and mosquito bites. She lived to 21 never having been indoors except for the one time I trapped her and had her spayed by the Wild Cat Coalation here in San Diego.
If I put one up it would attract a large hawk audience and be a coyote attractant.
