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.

Setting it up is simple—just plug it into an open outlet with no nearby obstructions like curtains or shelves to ensure good diffusion. It’s also drug-free and safe for cats, posing no risk to humans or other pets. However, it doesn’t have an automatic shutoff, so it needs to be monitored, and refills must be replaced monthly to keep working well.

While it’s effective for many, some cats may respond differently, and the diffuser should be used in the room your cat frequents most. It is a trusted, vet-recommended option for cat owners looking for a natural way to ease feline stress, but it requires consistent use and proper placement for best results.
