“In cats, chronic stress often disrupts digestion before anything else shows. FELOCITY helps calm that stress response, supporting a settled gut and an easier litter box”
The FELOCITY Diffuser was made for the cat whose stress shows up in there stomach. The vomiting, the smelly stool, the litter-box troubles owners are told to just live with. It releases two calming pheromones, F3 and CAP, odorless to you, where most diffusers use only one. Used daily, it's the drug-free way to keep her calm at the root and your peace of mind.
Setup is quick—after that, TheraPet runs on autopilot.
A unique pheromone blend you won’t find in any other diffuser.

"Feliway did nothing for her stomach. This one uses two pheromones, not one, and three weeks in, her stool firmed up and the smell is gone."
"My cat seemed perfectly happy, so I doubted it. But the vomiting was the real tell, and a month in, the cleanups just stopped."

Frequently Asked Questions
Many cat owners start to notice small changes within the first few weeks, such as a calmer, more settled demeanor.
However, every cat is unique. Your cat's personality, surroundings, and overall stress levels can all influence how quickly these changes become noticeable.
For the best effect, place the diffuser in a room where your cat spends most of their time such as the living room, bedroom, or a favorite resting spot. To ensure it works properly:
Each diffuser can cover up to 700 sq. ft. of open space, but barriers like walls, closed doors, and large furniture may reduce how far the pheromones spread.
For optimal coverage, many users choose to place 2–3 diffusers in different rooms throughout the home.
We provide plug types compatible with the UK, US, and AUS/NZ, and your order will be matched to your delivery location.
