Never seen guys break the bottoms of flower pots to make hides. Most of the time i've just seen them laid on the side and then just overhang some plastic greenery over it. It would work but not sure how something like terra cotta clay pots would be to clean snake piss off of. I use them for the potted plants in my snake cages but they never piss or poop on them. They are fairly porous and i have been told they are awesome for plants as they 'breath' unlike plastic or ceramic pots.
