The bottom in my cage is removable which I have covered with a fish tank background and poked some holes in for help draining. I have a tray under my cage to catch water that I got from LLLReptile, with a drilled hole for a bulkhead and a attached tubing that I got when I ordered my mistking, that goes through a drilled hole in my stand into a bucket under the stand. I just empty the 5 gallon bucket once a week.
