## At a glance

- Presented as support for calmer interactions in multi-cat homes.

### Product details

## Before you buy

- The maker advises plugging the unit into an open outlet with vents pointed upward and at least 4 feet of clearance. It recommends placing it where cats spend time, avoiding obstruction, and using an additional diffuser for areas larger than 700 square feet.
- The maker recommends replacing the refill monthly and the diffuser head every six months. It says to use only Optimum refills with the Optimum diffuser.
- The listing is inconsistent about pack contents: the title says a diffuser kit with a six-pack refill, while product details say 7 packs. The package inventory is not supplied, so confirm the selected listing's exact kit contents. The 30 minutes runtime also conflicts with the maker's separate claim of refill support for up to 30 days. Coverage is variously stated as 700 square feet and 700 sq ft. These details are listing claims, not independently verified measurements.

## A good fit for

- Cat owners seeking plug-in pheromone support for stress-related behaviors at home.
- Multi-cat households looking for a product marketed to ease tension between cats.

## Less suited to

- Buyers who need a confirmed list of included components before purchase, since the package contents are not itemized here.
- Buyers seeking a product with an independently established outcome or a guaranteed response from every cat.

## Customer feedback

The available customer evidence consists of aggregate ratings, with a generally favorable distribution alongside some lower ratings. That offers a cautious indication of overall reception, but does not identify what customers liked or disliked or establish how well the diffuser works for a particular cat.
