Purrfect Cat Calming Diffuser Refill Pack

The Purrfect calm cat calming diffuser refill pack keeps the peace going in your home — month after month, without interruption. Each refill delivers up to 30 days of continuous pheromone-based calm for anxious cats and multi-cat households, using the same trusted drug-free, sedative-free formula as your original Purrfect Calm kit. Cat anxiety doesn't take a break. The moment your diffuser runs empty, the pheromone signal stops — and stress behaviors like hiding, aggression, excessive vocalization, and urine marking can return quickly. Staying stocked with a Purrfect Calm cat calming diffuser refill is the simplest way to protect the progress you've already made. Replacing your refill takes less than a minute. Unplug, swap, plug back in — continuous calm resumes immediately. The formula is drug-free, sedative-free, and odorless — safe for cats and kittens of all ages and breeds. Free from sulfates, parabens, alcohol, and harsh chemicals. Purrfect Calm is part of the Petnatics pet health and beauty lineup. Every purchase is backed by our no-questions-asked money-back guarantee. Replace every 30 days. Never let the calm run out. Also works with FELIWAY Brand diffusers!
