The Kitty Pass XL Interior cat Door Large cat Hidden Litter Box Extra Large cat Door

My dad installed this for me in my laundry room door. He has done construction for years and said that he couldnt cut the full hole or it would compromise the structure of the door (slam the door and it could crack/break), Im not sure I believe him but was happy he found a way to make it work. Both my cats love the cat door and started using it immediately. My older cat cracks me up over it. When I get home from work (or wherever) she greets me at the garage door (I come in from the garage to the laundry room, the cat door is on the laundry room door), I give her a hello pet and then open the laundry room door to go further in to the house...she insists on staying in the laundry room until I close the door again, and then she comes through the cat door. It is a funny little routine. The liter box is in the laundry room. Having the door to the laundry room closed helps minimize the smell, but the cat door does allow some of the stinkier business escape. It isnt nearly as bad. I also installed a bathroom fan in the laundry room, on a motion sensor, so that helps pull the smell out of the room quickly. Doesnt 100% stop the fresh smells but does make it so the entire house doesnt smell like a cat box.
