The Menagerie provides a slow and “bumpy” vibration. The Cat-N-Mouse Tips were designed with a variety of textures to generate different sensations within the oral cavity and around the lips and face.  The reverse sides have many additional textures and “pockets” for the tongue to explore. Use the ears to scoop foods on either a smooth or textured surface! Or use the Bite-N-Chew Tips to vary jaw position.
