5 pressure treated 2x4x8. Framed in the doorway and installed the screen door. Still to do. I have some black 1/2" fencer wire coming. Going to turn it into a small catio. Total cost, about $240 for the wood, screen door and fencer wire. Already had all the screws etc. I needed.
Looks like the cats already know how to shred screen, better get the tough stuff.
That was a stray that we took in a couple winters ago. Once spring hit she didn’t want to be a indoor cat anymore. Unfortunately, I think a coyote got her. I saw one in the neighborhood and she never came back. But yeah, definitely going for shred proof on the deck.
