We have a plastic bottom, should we remove it and replace it with a mesh one for better drainage. It seems like you would have to tilt the cage up and back in order for it to drain out the tube. I see the other option is to just empty a tub under it every day and I definitively dont want to do that. Am I going to have to just raise up the cage so the water will come down to drain and drill through the plastic and then in through my table? I'm so sorry, I just cant figure this out.
