I think the tile would be fine it will be a pain in the butt to clean your cages but if your ok with that it should not be a problem. I use indoor/outdoor carpet in my display cages the kind they sell at lowes and home depot with the rubber backing. if you cut two pieces for each cage you will always have a clean one to swap out. you can't put them in the washing machine though they fall apart I hang mine on a fence with clothes pins outside and wash them with the water hose and let them dry in the sun then bring them inside and stack them up make sure they lay flat all the time or it will make a crease that will allow the snake to get under it. Some people say you should not use the carpet because you cant get it clean I have been using the same carpets for 8 cages for over 3 years without a problem.
