Key Takeaways
- The AeroKat is a feline aerosol chamber — a spacer device that catches medication from a pressurized inhaler so a cat can breathe it in through a face mask instead of being sprayed directly (Trudell Animal Health).
- Aerosol chambers are the standard delivery method for inhaled feline asthma treatment; a 2021 J Feline Med Surg study found chambers can carry bacterial contamination, which is why weekly cleaning matters (PMID: 32228277).
- The AeroKat chamber cost $61.95 on Amazon US as of September 22, 2026 (ASIN B005AIPRJG) — replacement masks are sold separately.
- Manufacturer guidance is to actuate the inhaler into the chamber and let the cat take roughly 7–10 breaths, counted on the Flow-Vu indicator.
- Cat-specific alternatives exist at lower prices — the Neobay chamber runs $34.99 with two mask sizes and a treat-guided Comfort Feeder that helps reluctant cats accept the mask.
The AeroKat chamber is the best-known spacer for giving cats inhaled medication, and it does that job well — but at $61.95 (Amazon US, September 2026) with masks sold separately, it is also the most expensive option in the category. A chamber's real job is simple: turn a puff of pressurized medication into slow, breathable mist so it reaches your cat's lungs instead of the back of their throat. Here is what the AeroKat is, how to use it, what it really costs over time, and when a lower-cost alternative like the Neobay chamber ($34.99, with a treat-guided Comfort Feeder) is worth considering.
A quick note before we start: this guide is written by the Neobay Pet Editorial Team, and we make a competing product. We've kept the facts verifiable either way — prices carry dated snapshots, and medical points cite published sources.
What Is the AeroKat Chamber?
Aerosol chamber — a hollow plastic spacer that attaches to a metered-dose inhaler (MDI) on one end and a face mask on the other, holding the medication suspended so a cat can inhale it at its own pace over several breaths.
The AeroKat, made by Trudell Medical International, is the original cat-specific chamber. It comes with two mask sizes (small and medium) to fit kittens through large adults, and a Flow-Vu indicator — a small flap that moves each time your cat breathes, so you can count breaths and confirm medication was actually inhaled rather than guessing.
Vets prescribe chambers because spraying an MDI directly at a cat's face fails on both counts: the fast plume can't be timed to a breath, and most of the dose ends up in the mouth or the room. Inhaled therapy delivered through a chamber is the standard approach for feline asthma, a condition estimated to affect roughly 1–5% of cats (Cornell Feline Health Center).
How the Chamber Delivers Medication
The mechanics are straightforward. You attach the prescribed inhaler — commonly fluticasone (Flovent) for daily control or albuterol for flare-ups — to the chamber's rear port. Press the canister once. The medication puff fills the chamber, and the droplets slow down inside it. Then you hold the mask gently over your cat's nose and mouth and let them breathe normally.
The Flow-Vu flap gives you the feedback loop: each flutter is one breath. Manufacturer guidance is to aim for about 7–10 breaths per dose before removing the mask.
Why can't I just spray the inhaler into my cat's mouth like the vet demoed with a tissue?
Direct spraying wastes most of the dose. A cat can't inhale on command in the half-second the plume takes to hit the back of the throat, so the medication deposits where it does no good. The chamber buys time — the drug stays suspended for several seconds, and the one-way valve keeps your cat's exhaled air from diluting it.
Using the Chamber: The Short Version
Shake the inhaler, attach it, actuate one puff into the chamber, then hold the mask over your cat's face until you count the breaths on the indicator. Reward with a treat afterward. Most cats need a training period before they accept the mask calmly — International Cat Care's step-by-step program recommends introducing the mask gradually with food, starting from placing treats near it and working up to full-face contact.
Be realistic about the timeline. In one r/CatAdvice thread, an owner reported a month of training before switching to gently holding the mask in place, and described finally reaching a one-person routine "all these months later."
Slow progress is normal, not failure. Our detailed walk-through covers how to give inhaled medication without the stress, and the guide to cat inhaler spacers explains the device category in depth.
What the AeroKat Costs — and What Replacements Add
Prices first, with dates. The AeroKat Feline Aerosol Chamber listed at $61.95 on Amazon US as of September 22, 2026 (ASIN B005AIPRJG). It is also stocked at Chewy and some veterinary clinics, and prices vary — a common experience on cat forums is hunting between retailers because "the cost is the main issue," as one r/CatAdvice poster put it before buying from Chewy.
The chamber itself is the entry price. Replacement masks wear out with daily use and cleaning, and buying a spare mask later adds to the total. If you want the full cost picture, our guide to sourcing replacement AeroKat masks and parts breaks down what wears, what's replaceable, and where to buy without overpaying.
For comparison, the Neobay chamber is $34.99 for a one-pack with small and medium masks included, or $59.99 for a two-pack with a backup chamber — useful for multi-cat households or keeping one at a second location. Prices are current as of September 2026 and can change; verify current listings before buying.

- Two chambers for multi-cat homes — no cross-contamination
AeroKat Alternatives: When Cost or Fit Is the Issue
Not every alternative is worth trusting — that skepticism shows up constantly in owner discussions, with people saying they "didn't trust other brands" and paid full price instead. So treat alternatives the way you'd treat any pet device: check that it's designed specifically for cats (not adapted from infant or dog products), that it has two mask sizes, and that it has a breathing indicator so you can count doses.
The Neobay chamber checks those boxes at $34.99. It adds a Comfort Feeder — a treat-guided attachment that lets you place food at the mask entrance so your cat voluntarily presses toward the mask instead of being pushed into it. That design directly targets the training plateau many AeroKat owners hit, where a cat will follow a treat partway into a mask-shaped object but refuses the final step.
For a feature-by-feature look, our AeroKat vs. Neobay comparison covers mask fit, indicators, and price, and the three-way comparison with generic chambers shows where budget options cut corners.

Frequently Asked Questions
Do I need a prescription for an AeroKat chamber?
The chamber itself is a pet accessory and doesn't require a prescription, but the inhalers that attach to it — Flovent, fluticasone, albuterol — do. Your vet writes the prescription; the chamber is just the delivery device.
How many breaths should my cat take through the chamber?
Manufacturer guidance is roughly 7–10 breaths per puff, counted on the Flow-Vu indicator. If your cat pulls away after 5 breaths, some medication is better than none — just mention it at your next vet visit.
How often should I clean the chamber?
Weekly is the common recommendation, and the stakes are real: a 2021 study in the Journal of Feline Medicine and Surgery tested cleaning methods on contaminated feline chambers (PMID: 32228277), and a 2023 study found bacteria in chambers from cats and dogs on chronic inhalation therapy (PMID: 36839547). Wash the mask and chamber per the manufacturer's instructions and let them air-dry fully.
Can I use a baby spacer (like an AeroChamber) instead?
It's not recommended. Infant spacers have human-sized masks that don't seal on a cat's face, and their valves are tuned to an infant's inhalation strength. A cat-specific chamber fits better and wastes less medication.
Is a cheaper chamber safe for my cat?
Chamber quality comes down to design fit, not medicine — the chamber carries no medication itself. Look for cat-specific mask geometry, two mask sizes, and a breathing indicator. If a budget option lacks those, the dose delivery gets less reliable.
What to Do Next
Ready for the full dose-by-dose routine? See our step-by-step guide to using the AeroKat chamber.
- Confirm the plan with your vet — which inhaler, what dose, and how many breaths per session for your cat's condition.
- Decide your budget: the AeroKat at $61.95, or a cat-specific alternative like the Neobay chamber at $34.99 with the Comfort Feeder for reluctant cats.
- Start mask training the same week the device arrives — gradual, treat-based, and unhurried beats a rushed first session every time.
