Josh's Frogs Frog Foam Terrarium Liners How it Works: Josh's Frogs Frog Foam Terrarium Liner is one solid piece of foam - no little pieces or loose fibers for your animals to get stuck on, or eat and become impacted! It is also very soft, preventing injury or damage to delicate amphibian skin. Think of Josh's Frogs Frog Foam as a high quality memory foam mattress for your amphibians! Frog Foam absorbs water and distributes it across it's surface, resulting in a moist, humid environment. It's blue color makes feeder insects stand out, resulting in a better feeding response from your pets. Frog Foam is 1" thick. How to Use: Frog Foam is easy to clean - simply spot clean when waste is visible. Remove Frog Foam from the habitat once a week, rinse out with water, spray to saturation or soak in Josh's Frogs ReptiSan, then rinse clean and replace in the enclosure. Simply pour water right into Frog Foam, and watch it get sucked up! You may wish to purchase 2 Frog Foams, so that you can alternate between cleanings. Pro Tips: The foam is easily cut with razor blade for a perfect fit for non standard sizes. As well, it can be cut to act as a "land section" for semi-aquatic animals or to sink a water bowl or other fixture into the substrate. What amphibians can use it?
