I highly recommend gettong UGODOG box. We have been trying to train Lily for a few months to go outside. I bought this and recieved about a week ago and she is already learning fast! She is going poo on it by herself without us telling her. This morning she went pee on it by herself. I wish we would have ordered this when we brought her home. It's great for me too cause I hate going outside every two hours! What I have been doing is laying a clean pee pad on the tray under the grids every morning. I will leave the same pad all day so she can smell where she needs to go (a clean pad is put in every night cause she will go on it in the morning). Poo I just take off grid from tray and drop poo in toilet. You do not have to buys pee pads, you can also use newpapers which I will do when I run out of pads.
HINT: If you feed a high quality food the poo will not be mushy and you can just drop in toilet with none left on the grates to wipe off.
The Wizdog is the same concept but reviews said UGODOG is better. I bought mine on Amazon, just do a search. Good luck
