Cats have nine lives! So, make every life more play inspired by sending your kitties into a field of Honeysuckle heaven with a spray of our Honeysuckle and Catnip oil blend on their scratcher, favourite bed, or teaser. A GREAT gift idea! Catnip can be given every other day to cats, but after a few minutes, its effectiveness wears off and your cat will need to be away from the catnip for a while in order to experience a reaction again. Catnip may not be well received by cats under a year old.
