The Smartpet mice, which can be filled with dry food, are an interesting possibility to give your house cat species-specific food. Simply fill the mice and hide them in your home and the hunt for prey can begin. With the slider, the opening can be enlarged or reduced to further increase the degree of difficulty. Several small amounts of food distributed throughout the day and through the night will prevent vomiting after a meal and also support the health and well-being of your cat. The interactive food dispensers encourage your cat’s natural instinctive hunting behaviour, so this toy is even tested and recommended by vets.
