I haven't had that problem. One time i feed her a nightcrawler and it got on the repti carpet. When she attempted to eat it, she bit and snagged some of the carpet. She started thrashing side to side thinking she was fighting the worm when in reality it was the carpet giving her a hard time. Also, it drys really fast, but when you wash it, it wrinkles and losses its shape a lil bit. Other than that, its proven to be useful and safe.
