I picked up the moss matt at the last show I went to along with the Exo Terra Exploraium. I plan to use this on my grey’s to hang them outside when the weather turns nice for some fresh air. On the moss matt, you can pull the threads off the base if you tug at it. The guys said the average frog would not be able to pull this off. I dunno and since my frogs are tong feed I’m not worried about it but I wouldn’t use this on free feeding frogs. I never thought of fleece, what a GREAT idea. I can put that in my CCC (critter care center) a.k.a. 10 gal tank. I have one set aside and ready in case I need to quarantine.
