The AeroKat Feline Aerosol Chamber (FAC) is designed to be used with a Metered Dose Inhaler (puffer) as recommended by a veterinarian to deliver aerosol medication to cats with feline asthma, chronic bronchitis or allergic rhinitis.
When the AeroKat FAC is attached to the puffer it allows your cat to breathe normally and inhale the aerosol medication which goes deep into your cats' lungs, where it is needed.

The Flow-Vu Indicator takes the guesswork out of using your cats' aerosol medication. The Flow-Vu Indicator will help you count the number of breaths your cat has taken through the chamber and may help to ensure there is a satisfactory seal between the muzzle and the mask, to optimize the delivery of the medication.

As your cat inhales, the bright green Flow-Vu Indicator will flutter or move towards the cat (if you have a good facemask seal). When your cat stops inhaling or exhales, the indicator will return to the vertical position.
The ideal time to activate the puffer is when your pet starts to inhale and the Flow-Vu Indicator is moving horizontally towards them
