What it works with

These refills are designed for use with a compatible cat pheromone diffuser set. Insert a refill into the diffuser, then plug the device into a standard outlet for continuous use. The diffuser plug is required and is not included, so this pack is best suited to households that already have a compatible device or are setting up a compatible one. For ongoing use, the manufacturer recommends replacing the diffuser device every six months.

The refill format can support use in a multi-cat home or across multiple rooms when paired with compatible diffuser devices. It is intended to help maintain a more relaxed environment and support comfortable behaviour around issues such as scratching, spraying, excessive meowing, overgrooming, hiding or restlessness. It is an ongoing environmental aid, not an instant fix, and responses can differ from cat to cat.

Best use cases

Use the refills where cats spend time, including shared areas in a multi-cat home or a room where a cat is often alone. Continuous operation makes the routine straightforward: fit the refill, plug in the diffuser and keep it in use as directed. For a household seeking day-to-day ambient support, this six-pack provides a longer supply than purchasing a single refill at a time. It is suitable for kittens, adult cats and senior cats, making it a practical option for homes with cats at different life stages.

Buyers describe a calming effect for some cats, with some noticing changes over time, while others report little difference. Feedback on effectiveness is mixed. Although the formula is described as fragrance-free, some buyers mention an unpleasant odour. These experiences are individual, so the product’s intended role is best understood as support for a calmer home environment rather than a guaranteed behaviour change.

Questions before you buy

Does this pack include the diffuser plug? No. The product is a pack of refills and requires a compatible diffuser plug, which is sold separately.

How long does each refill last? Each refill is designed for up to 30 days of continuous use. Actual results may vary with use and the individual cat.

Can it be used for cats of different ages? Yes. The refills are described as suitable for kittens, adult cats and senior cats.

Is it worth it?

If you already have a compatible diffuser and want a convenient supply for ongoing use, TopSum’s six-refill pack keeps the routine simple and is intended to support a more comfortable home for cats of all ages. Its fragrance-free formula and multi-room or multi-cat use make it a considered fit for households looking for continuous, room-based calming support.
