Zesty Paws Calming Diffuser Refill for Cats is here to help your feline friend find their Zen. As pet parents, we understand the worry and stress that comes with seeing our cats deal with anxiety. But with this diffuser refill, you can help your cat relax in a natural and gentle way. This veterinarian-formulated diffuser refill mimics the calming pheromones that cats produce, helping to reduce signs of stress and support a sense of calm and security. Featuring a pleasant scent, this refill diffuses areas as big as 1,000 sq. ft. and lasts for up to 30 days, keeping your cat purring with contentment. Simply plug the Zesty Paws Calming Diffuser (sold separately) into an indoor wall outlet and let it work its magic. In as little as two days, the fragranced pheromones can help reduce scratching, urine spraying, excessive grooming, and other signs of stress. Whether you’re dealing with behavioral issues or just want to create a peaceful environment for your cat, this diffuser refill has got you covered.
