Whats most important when you are remodeling an out door deck to be a cat stud house?

We need to redo it all and I want some ideas so this area is good for all 3 of these A cat playroom Normal outdoor deck for people to sit out in the summer AND A place for a male cat and a lady cat visiter.

Keep in mind most of the time all our cats can go out there and we use it most evry day our selfs. So it cant be remodeled so it only a cat stud house. And so far this cat dont spray to speak of at all. And anyways Im not clear if hell have his balls his hole life or not. So I dont want no ideas that have a ceement floor or all tiles like a bath room.

The floor is wood and that do concern me a little in case he do spray. It gonna stay WOOD. What coud go over it tho? Some thing that can come back up like rubber carpet? Is there rubber carpet?

My daughters Bengel cat dont live out on the deck by him self. Hes in with us and gos out in that room to play like the other cats. Same.

Our deck is all ready mostly closed in and that where we all ready have set up as our cats out side play room. See if I opne my back door I,m on part of the deck closed in. Then that part got 2 door on eether side. One go to the not closed in part of the deck and the stares. The other door go to the other closed in part. And that door have a cat door in it. Theres a table and chairs in there for us it is set up for the cats tho. The front wall to it is sliding glass and they stay open if it aint real cold. Theres regular screens and wire mesh both.

Now we added another little room to the space with another door with a cat door from it. And a cat can get in to either one threw the cat doors threw the back of my kitchen. But they are seprate big room and little room unless we open the big door or unlock the cat door in that door.

The big room got all kinds of things for cats. in the little room there less stuff cuz its smaller its got 3 shelfs at diffrent levels a sonatube cat tree 6 foot tall with hideing and sleeping places and pertches.

This little room is for if a girl cat visits so she and Viney can smell each other and to be sure they dont hate each other.A cat in one room can be nose to nose with cat in the other room theres wire mesh wall between them tho.

I woud be very happy to hear your ideas and to see any good pictshures that can help us come up with our own ideas.
