i use the pet-a-potty and love it. we don't even need the drain pan in it with 2 small maltese, the sod soaks up the urine. i change the sod out about once a month or two, depending on the time of year.
I bought one and my girls wouldn't use it. I sent it to my son to see if his two would but they wouldn't use it either. :blink:
It would be perfect for winter and rainy days so I sure wish they would have. :blush:
