Many of you may be suffering what I have been going through with the cat urinating on the floor while in a normal cat box. Struggled with this for months until I came up with an inexpensive fix. A storage container taller than the usual cat box and cheap to buy and easy to make. I have been experimenting with higher and higher entry points and finally 7 inches high off the ground is the winning number and wide enough for them to enter. I keep it covered to keep sand inside. Purchased at Walmart. Cut opening with an electric hand held dremel.
