Is there ANY way to turn your indoor/outdoor cat into..  

I just adopted a cat named Freddie who has been an outdoor cat for 6 months. He is now purely an indoor cat. He seems to be taking it well, no undue meowing to get outside and no door darting so far. I think you could try keeping them indoors and see what happens some cats take to it readily and some never get over being outdoor cats.

I'm personally interested in just the opposite; turning my indoor cat out door. He's adorable and I love him but he's developed some habits lately id rather he do outside. lol.

It is possible- they may not be thrilled with it at first but it is possible.
I had 17 cats when I moved to a city apartment where it wasn't safe to let them out..
They had to stay in for 4 years in first one apartment and then 5 years in another.
Then we got a house.. and they started going in an out again..
We did lose 2 during one of the apartment stays who escaped (one after sneaking into the hall while a neighbor was watching them while I was away for a few days) and another after some kids poked a hole in my bedroom screen window and she squeezed thru the hole.. I am still upset as these were my favorite cats and I put up a search and could never find them..
Started wondering if I had just taught them the neighborhood first if they would have never got lost... :(

I have never has much success doing this, making sure they are happy with their potty box is primary, and making sure that they get enough exercise inside will help. Never let them out after they have been fed only before, that way the motivation to return is strong. This is all I can suggest.
