We have a wide variety of Enrichment Feeders including eMats (also known as Lick Mats) eTrays eBowls and eCoins. These Enrichment Feeders come with different levels of difficulty and a wide variety of fun and interesting pattern designs that do a great job of retaining the treats. Patterns that are shallower and have greater spacing make it easier for dogs to lick the food out. Patterns that are deeper more complex and have tighter spacing present more difficulty. Our Enrichment Feeders are heavier and sturdier than others on the market. We made them this way so they stay in place and don?t move around too much frustrating your dog?s licking efforts. This also makes them easier to handle and manage especially when putting them in the freezer. Like all SodaPup toys Enrichment Feeders are made in USA from the safest proprietary materials that are non-toxic pet-safe food-safe and top rack dishwasher safe. Many types of foods can be used with our Enrichment Feeders. Peanut butter or plain yogurt are
