## Description

The plug-in format provides continuous pheromone support for cats at home. The EIUIO-1 set includes two diffusers and four refills. It is designed for multi-cat households and everyday situations that may bring changes or stress.

## How it fits
Use the diffuser in a room where your cats spend time, such as a bedroom or living room. Plug it into an open wall outlet and let it provide ongoing support without adding a daily spray or pill routine. The product is designed to help address behaviors associated with stress, including hiding, scratching, urine spraying, nervous behavior, and conflict between cats.

It can also support a calmer environment during changes such as introducing a new pet, moving to a new home, having visitors, or experiencing loud noises like fireworks or thunderstorms. For example, placing a diffuser in a shared living area offers a consistent option for a multi-cat home while cats adjust to a new household routine. The set is designed for rooms up to approximately 750 sq ft.

## Strengths
Each refill provides up to 30 days of continuous support, and the four included refills are presented as up to 120 days of use. Having two diffusers gives households another unit for a separate room or area. Together, the plug-in format and refill supply make this a practical choice for ongoing use rather than a solution that requires applying a spray each time a stressful situation arises.

The pheromone technology is intended to support calm behavior, not to replace a cat’s familiar routines. It is suitable for kittens, adult cats, senior cats, and homes with multiple cats. Customers describe a calmer atmosphere and convenient everyday use, some also note that the diffuser operates quietly and that its scent is not too strong. These are individual customer impressions, while each cat’s response may differ.
