Using the Catit Senses 2.0 Self Groomer is easy. First, pick a spot at your cat's height on a flat wall or a corner surface. Then, use the included adhesive strips to attach the holder to the surface. Next, place the brush into the holder. You can add the provided Canadian Catnip herb to the compartment in the brush to attract your cat. As your cat rubs against the brush, it will help remove and collect loose hair. When it comes to maintenance, simply disassemble the brush from the holder. It's easy to clean under running water. Keep in mind that while the materials are BPA - free, check the adhesive strips regularly to make sure the groomer stays firmly attached. If your cat seems to lose interest, you can replace the catnip herb with a fresh one to keep the fun going.
