## Description

A pheromone diffuser kit helps create a more settled home environment without adding fragrance. The TopSum TS03 comes with two diffusers and two refills, making it practical to set up in more than one room or in a home with multiple cats. Each refill is designed for up to 30 days of continuous use. It’s a convenient approach when you want ongoing support at home rather than a product used only in response to a particular behaviour.

## Everyday use
Set a diffuser up in a room where your cat spends time, such as a shared living area or a favourite resting spot. For a multi-cat household, having two diffuser devices gives you the option to place them in separate rooms. The refill fits into a compatible diffuser and the device plugs into a standard outlet, so the routine is straightforward: keep it in use and replace the refill as needed.

The formula is fragrance-free, a useful detail for homes where added scents are unwelcome. The product is described as suitable for kittens, adult cats and senior cats. Its intended role is to support a calmer environment around behaviours such as scratching, excessive meowing, overgrooming, hiding or restlessness. Individual cats may respond differently, so think of it as ongoing environmental support rather than a guaranteed change in behaviour.

## Benefits
Two diffuser devices and two refills let you begin with more than one setup, instead of choosing between a single shared space and a separate room. That can be helpful when cats spend time in different parts of the home, or when several cats share their environment. The refill format also makes regular use simple: insert a refill into a compatible diffuser, plug it in and replace it when needed.

Buyer feedback often describes cats as calmer, with some owners also noting less conflict between cats. Other comments vary on odour and durability. The product itself is described as fragrance-free, and each refill is stated to last up to 30 days, these details give a clear basis for choosing it as a continuous-use option. If you’re weighing a plug-in approach against a product used only at specific moments, this kit is designed for ongoing use in the home.
