Opening in wall for cat

/ Opening in wall for cat #11  
I have two cats trained to open a flap that is held closed by a spring. It took about two weeks of closing the door a little each day and now they just push it open and slide through. They also have learned to tuck their tails in so the door does not catch them. Both sides are inside the house so no unauthorized entries.

They can't go the other way but that was the design. If they are upstairs they can go to the basement to the liter but then they are stuck there. Well except when my dog pushes the door open with her nose to see where her buddies are and they slide on through. I could not figure out how the cats were opening the door from the basement side until saw the dog spring them.
