They are very thin. They are a thin piece of plastic sheeting covered with a very thin layer of cotton fabric. These ceilings are designed for cages with a barrier between the animal and the ceiling. I've read the description many times and haven't seen it anywhere. My animals mostly stand in their own dirt. I had to change them several times a week. They chewed it too. Then I saw that on the back there is a notice to only use in cages with a barrier in between. I still use them because I feel stuck and don't want to just throw them away with a layer of shredded pet litter. This works better, but the linens soak up their mess. I have to use 2 due to the size of the tank and am now doing 2 coats (4 coats) plus on top. Disappointed with the price even though they are perfect for our glass aquarium. They'll be gone in no time (thankfully) so this is an expensive option.
