The latest addition to the Catit Senses series is a highly entertaining, interactive feather toy shaped like a mushroom. As your cat approaches, a feather will randomly pop out from one of the 8 openings covering the toy, stimulating your cat to play! The feather will randomly appear from an opening below or on top of the mushroom. The Catit Senses Mushroom can be set to two modes: sensor and continuous. When set to sensor mode, the built-in sensors will pick up on your cat's movements, activating the toy. The Catit Senses Mushroom takes 3x AA batteries (not included).
