Stimulate your mutt ...while slowing their intake.

Stimulate your mutt…while slowing their intake. Transform your existing dog bowl into a slow feeder in one simple step. The universal design has wings that bend to create multiple compartments around food, encouraging your dog (or cat) to 'hunt' for each bite. Slower feeding can help improve digestion and reduce bloating.

A great interactive dog feeder that will help  your furry friend slow down a little.  Don't we all need that sometimes?

Features:

• Wings bend to fit your existing bowl or can be cut down to the perfect size.
• Six suction cups help secure the slow feeder insert in place. Perfect with non porous like stainless steel, plastic, or ceramic bowls.
• Works with bowls that have a base at least 5" in diameter or more. The 4.5" solid base is constructed of a strong PP material, with flexible TPR wings that extend to 7.5" in diameter.
• Easy to clean, dishwasher safe.
