Therapet MD Cat Calming Diffuser Refills, 2-Pack, 60-Day Supply for Stress Support

Therapet MD Cat Calming Diffuser Refill Kit is a pheromone refill set designed to support calmer cat behavior, with two 48 mL refills providing a 60-day supply.

• Two 30-day refills, 48 mL each — maintain ongoing diffusion for up to 60 days.
• Dual facial and maternal pheromones — support cats experiencing urine marking, scratching, excessive meowing, or stress.
• Clinically proven to reduce fighting and aggression by up to 83% — support more peaceful multi-cat households.
• Coverage of up to 700 sq ft per refill — diffuse pheromones across a home environment.
• Made for the TheraPet MD Cat Calming Diffuser — the diffuser itself is not included.
• Drug-free, vet-recommended formula — made without harsh chemicals, artificial fragrances, or toxins.

Changes at home, travel, thunderstorms, and introductions to a new pet can create stressful situations for cats. This refill kit is made to continue pheromone diffusion in those settings, including homes where tension between cats, spraying, or other unwanted behaviors are a concern. Its pheromone blend mimics natural feline signals associated with comfort and security.

What behavior support is the formula designed to provide?

The dual-pheromone formula is designed to help ease stress-related behaviors and support harmony between cats. Its intended uses include urine marking, excessive meowing, and scratching, as well as tension during household transitions, vet visits, or new-pet introductions. The stated clinical result is a reduction in fighting and aggression of up to 83%; individual results are not guaranteed.

• Uses facial and maternal pheromone mimics.
• Developed with veterinarians and recommended by veterinarians.

Which diffuser does this refill fit?

These vials are made for use with the TheraPet MD Cat Calming Diffuser. The diffuser is not part of this refill kit, so you need that diffuser to use the vials. To replace an empty vial, remove it and twist a new refill into place.

• Replacement is done by removing the empty vial and twisting in a new one.
• The refill format lets you continue using the compatible diffuser.

Who can be around the pheromone solution?

The drug-free solution is described as safe for cats of all ages, people, and other pets. It contains no harsh chemicals, artificial fragrances, or toxins, making the formula suitable for use in a shared home environment.

• Natural pheromone-based solution.
• Each refill is intended to cover up to 700 sq ft.

Cat households looking for ongoing pheromone support—particularly homes managing stress-related behaviors or tension between cats—are the intended fit. The kit is a replacement supply for the TheraPet MD Cat Calming Diffuser, rather than a standalone diffuser; its two refills provide up to 60 days of continued use.
