O boy did you get fancy with those I tryed using the ones with the top and he wouldnt go in so I had to take the lid off. The one I have now is just a normal rectagle one but huge its impossible for him to miss, was expnsive though. You must be frustrated they are expensive dont give up on him though:(   good luck
