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.

We have a cat that loves to run out the door when you open it. I need to build a screened in porch to keep him from getting out.

Yours looks great.

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.

Good work, it looks fantastic and your cats will love it, good on you for keeping them safe as well
