The TherapetMD Cat Calming Diffuser is designed to help reduce anxiety and stress in cats using a dual-pheromone technology that mimics natural calming signals cats use. It covers up to 700 square feet, making it suitable for most homes or multi-cat households. Many users report a noticeable reduction in common stress behaviors like spraying and scratching, as well as less fighting between cats.

The diffuser is very easy to use — just plug it into an outlet and it works continuously for about 30 days per refill without any strong smells. Its low-glow indicator light is subtle, which helps maintain a calm environment, though it might be hard to see in bright rooms. Safety-wise, it’s vet-recommended and chemical-free, making it a gentle option for cats, other pets, and humans alike.

The calming effects may take a few days to become noticeable, and you’ll need to remember to replace the refill monthly for ongoing benefits. The diffuser’s effectiveness can vary depending on the individual cat’s sensitivity to pheromones. If you have a multi-cat home or a cat prone to stress during events like thunderstorms or vet visits, this diffuser can be a helpful, hassle-free solution to create a more peaceful atmosphere.

The FELIWAY Optimum is a plug-in diffuser designed to reduce stress-related behaviors in cats using a drug-free, non-sedating pheromone formula. With a coverage area of up to 700 square feet and a duration of effectiveness of 30 days per refill, this product is ideal for homes with cats that exhibit scratching, urine spraying, conflicts, or excessive hiding. The diffuser is easy to use – simply plug it into an open outlet ensuring there is 4+ feet of space around it, and replace the refill monthly.

One notable safety feature is that the pheromones do not affect humans or other pets. However, it’s essential to use only FELIWAY Optimum refills with the diffuser and replace the diffuser every six months for optimal performance. Some users might find the recurring monthly purchasing of refills a bit costly, and the diffuser's performance can be compromised if placed inappropriately, such as under shelves or near litter boxes.
