We have two cats, Bamboo and Panda. Panda, unfortunately, is dumber than a stump. I would very much like to leave our glass door open so that Sparrow can go in and out onto the deck, and so the cats could go out there too, but every time I let Panda out on the deck he would jump off, land on his face, and cry at the basement door to be let in.
Yeah, he's a moron. Pretty, but stupid.
So here's what I did. I went to Lowe's and bought some plastic netting for $13. Then I bought zip ties for $1. Then I zip-tied the netting to my deck. That part was easy.
The problem was getting the netting hooked to the deck itself, so that the Stupid One couldn't climb underneath it and attempt to fly again.
One borrowed ladder, 3 near death experiences and 15 nails later, the cats were able to go out on the deck without supervision for the first time. Panda, as expected, poked at the netting and tried to get out, but he was thwarted. He glowered and yowled for a few minutes but finally decided to just chillax.
It was a good way to spend a Saturday.
