Keep your pet happy and animated with the duvo plus Wobble `n Snack ball, a refillable snack dispenser for puppies, small dogs and cats. It keeps their brains and bodies active while they hunt for a tasty snack. Fill the ball with dry food or treats. When your four-legged friend pushes the ball with their paws and makes it wobble, food randomly falls out of one of the openings. This fun reward will encourage them to play and exercise more. This challenging way of eating means that your dog or cat will feel that they have had enough to eat sooner. Eating less quickly improves general health and helps prevent stomach torsion, flatulence and obesity.
