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

I absolutely love this product. It worked great for us to put on our basement door and then the door to the litter room. Now we dont have to leave the doors open and it the largest size was big enough to fit my 30 lb cat. The reason I have 4stars for easy to install is because the pattern they give you, you then have to cut out and then trace which can cause it to be uneven. If they just gave you the pattern already cut so you would only need to trace then it would be easier. I did find it took some very careful cutting because we did have the raised panel boards so you have to be very careful. But overall super awesome product and it looks wonderful on the door compared to other plain cat doors. LOVE LOVE LOVE
