I would ask in the comments on the video. I've never seen those before. If the bottom is solid, they're a bad idea, but I suppose you could easily remedy that with a dremel tool or something. Personally, I don't think I'd like them just for the simple fact that about 80% of the time I want to get to my snake, I have to lift a hide off of her. I'd end up spilling that water bowl every time. lol.
