This nice large catio provides lots of space for a group of lucky kitties in their new home.

Lots of shelves offer plenty of prime perches for looking out into the yard.  Strong wire mesh hardware cloth on the walls allows an open feeling but keeps the kitties safe and secure.

The metal roof provides shade and also makes the catio usable when it's raining.

Access to the catio is through a window - and these windows were perfectly suited for a high quality metal and glass window insert unit with a cat door in the middle.  With a bunch of cats, there was always the issue of one being obstinate and blocking the kitty door - so that possibility was avoided by putting a kitty door in both windows.
