Take a new approach to behavior support with the Calm Paws Calming Disk Cat Collar Attachment. Using premium essential oils that have a soothing effect on your anxious cat, this disk simply slides onto most standard collars or harnesses so he can breathe in the calming scent. An innovative way to supply constant support day and night, it’s especially great during stressful situations to minimize anxious behaviors. You can also use it with Calm Paws Inflatable Collars (sold separately) to help support pets through the recovery phase after surgery, when use of surgical collars is recommended. It even glows in the dark!
