I used paper towels for years, and it happend a few months back one of my geckos was eating and grabbed the tip of the paper and swalowed a piece by mistake, I got SUPER worried (it was a very small piece, but yet, they have very small stomachs), anyways, my gecko was just fine but I wanted to look for a solution for this, I wanted to prevent it from happening again, and I found one product that is called SCOTT DURAMAX in my country (I am not sure about the name there, but I am sure you can find something similar, since I doubt there is something in my third world country that you guys can´t up there), this is it:

It is a type of reusable paper towel, it is not cloth but it is also not 100 % paper, it is very difficult to rip, even for a human, it works great, and you outrule the risk of it happening again. I completely changed to this product, which is a bit more expensive than the normal paper towels, but by no means is it expensive, and you don´t need to change it so often, just keep it moist, they have no way of ingesting it.
