Soothe the mood with every use! Calming Chamomile litter crystals help fresh your litter box while creating a calming atmosphere with specially crafted combination of odor-concealing Arm & Hammer™ Baking Soda and soothing, pleasant essential oils. These non-toxic fragrances are known for their calming properties, and once they are sprinkled into your litter, they will release a light fragrance every time your cat uses the litter box. Our specially crafted aromatic fragrance crystals are designed to be added to your cat's litter, effectively controlling odors while providing a gentle and non-intrusive way to introduce aromas that promote a calming, inviting environment in your cat's most-used area. Our Calming Chamomile blend includes both chamomile and bright, citrusy bergamot, creating a pleasant scent for any litterbox area. This product can be used with your preferred litter, simply sprinkle into your litterbox after every use. The crystals are water soluble and non-toxic, leaving no residue when they break down over time. Instructions: Fill cap with crystals. Sprinkle evenly over litter. Use more for larger boxes, less for smaller boxes. Be sure to replace cap tightly after use. Crystals are water soluble, so they will break down over time, leaving no residue. Use every time you scoop for a refreshing scent.
