Our vet approved, drug-free formula is scientifically proven to help cats feel safe, happy and relaxed while reducing uncool behaviours. Read more

Cats are creatures of habit, so even the slightest change can leave them feeling out of sorts. Fireworks, parties or changes in the home can make cats feel stressed and uncomfortable. Furniture scratching, urine marking, fighting, overgrooming and lack of appetite are some of the ways our cats express their discomfort. Chill Out releases calming pheromones that your furry friend will subconsciously associate with a sense of security, helping them feel safe, happy and relaxed.

Vet Approved

Zoe the Vet

"A feline pheromone diffuser is a great choice for anxious cats, especially those displaying stressed behaviours such as over grooming or urine marking. The ease of a plug-in alleviates further stress caused by physically medicating. That's why Chill Out is a great alternative to drug therapy and will reassure your cat they are in a calm, safe environment."
