10 Best Calming Plug In For Cats 2025 in the United States

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.

FELIWAY Optimum provides a reliable and scientifically-backed option for cat owners looking for an effective solution to manage their pets' stress-related behaviors.

The ease of use is a strong point, as it just needs to be plugged into an open outlet with proper ventilation. The diffuser needs a refill once a month and the device itself should be replaced every six months. Users have reported significant improvements in cat behavior, with many noting reduced conflict.

It is essential to use only FELIWAY refills and diffusers for optimal results, which might be a drawback for those looking for compatibility with other brands. This product is suitable for multi-cat households experiencing issues like fighting or chasing, backed by extensive research and vet recommendations.

Additionally, the pheromone diffuser covers an area of up to 400 square feet, making it suitable for medium to large rooms. Ease of use is a plus, as these refills only need monthly replacement and the diffuser itself can be used for up to 12 months. However, the product is only compatible with Comfort Zone diffusers, which might be a limitation for some users.

Another potential downside is that it must be used properly and plugged in the correct position to avoid issues like discoloration, odor, or leaking. The Comfort Zone MultiCat Diffuser Refills are a dependable and safe option for cat parents looking to reduce stress and promote harmony among their feline companions.
