We tried putting the pad on top of the grass, because I did not come back here to read until now.
She has continued to go on the pad even though it is on top of the grass. The only downside thus far, is she likes to lay on it.

I don't exactly want to pet her after she has laid on a wet pad.
I will get out the platform and see how it goes. I will report back tomorrow evening most likely. I hope she won't mind jumping up on it to do business.
