The Attachable Licking Mat is a must-have Fluff Trough accessory. The Attachable Licking Mat attaches to the standard Fluff Trough base to provide a safe, ergonomic enrichment activity for dogs and cats. Simply spread your pet’s favorite snack (like peanut butter, yogurt, fruit, etc.) on the FDA approved silicone lick mat and place it on the holder that attaches to the Fluff Trough base. Using the textured mat can be a soothing distraction for nervous pets, as licking can help calm their anxiety and help pass the time. This does NOT fit the XL size base from the Fluff Trough XL Silicone Insert Set.
