As said above, yes. Put a plant under like camimom said. You'll go through more water than you expect. The best and easiest drainage i have found so far is..
Go to walmart or somewhere like that and get storage shelving. I have plastic ones with solid shelves, but the slit ones would prob be better. But with the plastic ones, i just drilled a 1 inch hole in the top shelf. Then i drilled a few holes in my plant pot, and one (or a few) small holes in the middle of the cage. place the pot over that hole and the water should go down the holes you made into a bin you can place on the next shelf down.
