Our Florida home does not have a catio like our West Virginia home but we do have a Florida room that is a little bit like a catio. It is surrounded by big windows and the cats do enjoy being out there.
What makes it different is the glass windows. The feeling of being outside, the sounds and the smells, are lost when the windows are closed, and they are usually closed because the air conditioner is running.
Now that winter is coming we should be able to open them a little but, unfortunately, opening them more than three or four inches will likely result in Frankie or Chris pushing the screen out of the frame
I just need to make a point of bringing them out for walks when I can.
