Using the Catit Senses 2.0 Catnip Spray is easy. Just spray it on cat toys, fabrics, or scratching posts to attract your cat and make them play or scratch there. When using the spray, always keep an eye on your cat. Since cats have different sensitivities to catnip, you need to adjust the amount of spray used. If you use too much, your cat might become aggressive or hurt itself. Also, never spray it directly on your cat or other animals. To maintain the spray, keep it in a cool and dry place. That way, it will stay effective for a long time and continue to bring joy to your cat.
