Okay, that’s it. I think you should receive the kitty owner of the day award for that enclosure! That’s absolutely the best solution for kitty outdoor time.
We once had a wonderful screened porch our fellas could languish on. They loved it so much it was hard to get them to come in at night. The porch afforded them all the joys of outdoors without any of the dangers.
Yes they love it! they go out in it all night long and when the dawn comes, and I open the back door to let them in for their breakfast, it sounds like an elephant stampede as they make their way thru the tunnel, HOP onto the Rubbermaid cushion storage box that serves as their ramp and launch themselves at me for the official 'opening of the cans' for breakfast! LOL LOL It affords me a good laugh to greet each morning! What a delight they are.
