The AeroKat* Feline Aerosol Chamber is the spacer that lets you give your cat a human metered-dose inhaler — the delivery device vets rely on for feline asthma and chronic bronchitis. The inhaler puffs into the chamber, the medication is held there, and your cat simply breathes it in through a soft mask at their own pace. It's a device, not a medication, so no prescription is required for the chamber itself.
A metered-dose inhaler is designed for a person who can press and inhale at the same moment. A cat can't co-ordinate that — and puffing an inhaler at a cat's face without a chamber mostly sprays medication into the room. The chamber solves it by holding the dose so your cat can take several ordinary breaths to draw it in, which is what actually gets the medication down into the airways rather than onto the fur.
The AeroKat's Flow-Vu* inhalation indicator is the part that makes this reliable at home. The green indicator moves toward your cat with each breath in, and returns upright as they breathe out — so you can see that the mask is sealed properly and count the breaths, instead of guessing whether the dose went in.
If your vet has prescribed more than one puff per dose, give them one at a time and wait about 30 seconds between puffs. Most cats accept the mask within a week or two if you introduce it gradually with treats and praise rather than restraint. Your veterinarian sets the medication, the strength and the number of puffs — follow your prescription exactly.
Clean the chamber weekly: take it apart, soak the pieces for about 15 minutes in warm water with a mild dish soap, rinse, and stand them upright to air-dry for at least 12 hours. Don't put it in the dishwasher, don't boil or sterilise it, and don't scrub inside the barrel — the interior coating is what keeps the medication in suspension. With regular daily use, the manufacturer recommends replacing the chamber every 12 months.
The AeroKat fits any standard metered-dose inhaler, including the two most commonly prescribed for cats:
Many cats on a long-term asthma plan are prescribed both, and a single chamber is used for each. Those medications are prescription-only — upload your vet's prescription here and a licensed pharmacist will verify it before dispensing.
No. The chamber is a device and contains no medication, so you can order it on its own. The inhaler you use with it does need a prescription from your veterinarian.
The masks are personal-fit items, so a chamber is best kept to one cat. Ask your vet if you have a multi-cat household on inhaled therapy.
Watch the Flow-Vu indicator. If it flutters toward your cat as they breathe in, you have a good mask seal and the medication is moving. If it doesn't move, reseat the mask and try again.
It's very common at first. Introduce the chamber over several short sessions — let your cat sniff it, reward them, then build up to a few breaths — rather than forcing it in one go. Most cats settle within one to two weeks.
Use the AeroDawg canine chamber for dogs — it's sized for a dog's muzzle and comes with dog masks.
