Tallew Cat Calming Diffuser Refills, 16-Pack with GABA and Pheromones

Tallew Cat Calming Diffuser Refills are a non-drug plug-in refill set designed to help cats feel calmer, with 16 bottles and a dual GABA-and-pheromone formula.

• 16 refills, 48 ml each, with up to 30 days of use per bottle and up to 480 days total — keeps refills available for ongoing use.
• GABA combined with pheromones — supports calming through emotional and instinctive pathways.
• Coverage up to 700 square feet (about 65 m²) in open space — helps serve a larger shared area.
• Suitable for cats of all ages and breeds — provides a plug-in option for multi-cat households.
• Non-drug calming approach — made for everyday stress and related behaviors.

Changes in the home and everyday nervousness can be associated with stress behaviors such as scratching, spraying, fighting, and restlessness. Tallew refills are made for use in the rooms cats visit, helping create a calmer environment without a drug-based approach. In homes with several rooms, more than one refill may be needed to support coverage across the spaces cats use.

How does the calming formula work?

The formula combines GABA with pheromones to support cats through both emotional and instinctive responses. This dual approach is intended to offer broader calming support than a single-pheromone product. It is designed to help cats feel more at ease and settle into a comfortable resting routine.

• Uses both GABA and pheromones in one refill.
• Made to support a calmer response to everyday challenges.

Which diffuser heads fit these refills?

Tallew refills fit common electric warming cat-calming diffuser heads. They are not compatible with ultrasonic, misting, or essential-oil diffusers, so match the refill to a warming plug-in head.

• Use with an electric warming diffuser head.
• Not for ultrasonic, misting, or essential-oil diffuser systems.

Where and how should I use a refill?

Plug the diffuser into an outlet in a room your cat frequently visits, with the vent facing upward. Leave the surrounding area open so the pheromones can disperse; avoid placing the unit beneath shelves or behind doors, curtains, or furniture, which can interfere with diffusion.

• Continuous use for two weeks helps decrease unwanted behaviors.
• For the stated open-space coverage, keep the outlet area unobstructed.

Tallew Cat Calming Diffuser Refills suit cat households looking for a plug-in, non-drug way to support calmer behavior, including homes with cats of different ages or breeds. They are intended for compatible electric warming heads and for use in the areas cats regularly occupy.
