What Is a Cat Inhaler Spacer?
A cat inhaler spacer is a small holding chamber that attaches to a Metered-Dose Inhaler (MDI) on one end and a soft face mask on the other. When a cat takes a breath, the spacer captures the medication from the MDI and delivers it slowly into the lungs — turning a quick puff of spray into a controlled, breathable mist that a cat can inhale over 5–7 breaths. Neobay's cat inhaler spacers are designed specifically for feline anatomy, with a food-guided Comfort Feeder that helps cats accept the mask calmly.
A cat inhaler spacer (also called a feline aerosol chamber) is a prescription-compatible medical delivery device used alongside veterinarian-prescribed MDI medications such as fluticasone (Flovent) or salmeterol. It is not a medication itself and does not replace a veterinary prescription — it is the bridge between a standard human MDI canister and a cat's airway. As a direct AeroKat alternative, Neobay offers the same chamber-and-mask functionality plus food-guided training assistance.
Because the chamber holds the medication in suspension for several seconds, even cats that breathe shallowly or briefly hold their breath still receive the full prescribed dose.
Why Cats Need a Spacer — And What Happens Without One
Before inhaled therapy became standard, cats with chronic respiratory conditions were typically treated with oral or injected steroids (prednisolone). These system-wide medications work, but they come with well-documented side effects in cats: increased thirst and urination, weight gain, risk of diabetes, and behavioral changes. Inhaled medication delivered through a spacer acts locally in the lungs — the same symptom relief, with a fraction of the systemic exposure. That is why veterinary guidelines for feline lower airway disease now list inhaled therapy as a first-line long-term option. Whether you choose an AeroKat chamber or a Neobay spacer, the delivery principle is the same.
Cat Spacers vs. Human Spacers: Why They're Different
Human spacer chambers are built for cooperative adult patients who can inhale on command. Cats breathe at their own pace, often shallowly, and need a mask that seals gently around a furry face. A purpose-built feline spacer like Neobay's has three features no human spacer offers: a low-resistance anti-static chamber (so medication does not cling to the walls), two mask sizes for kittens and adult cats, and a food-guided Comfort Feeder that turns mask training into a positive experience rather than a restraint event. Most cat owners comparing AeroKat alternatives find that switching from a human spacer to any purpose-built feline chamber makes daily treatment noticeably easier.

Designed With Your Cat in Mind
Every Neobay spacer is built around one constraint: cats cannot be told to breathe in. A device that works on a human adult — push a button, inhale, done — fails completely on a small animal that does not understand what is happening. The four design choices below all trace back to that single problem.
Food-Guided Mask Training
The Comfort Feeder is a small reservoir at the end of the mask that holds a dab of wet food, a squeeze of Churu, or a crushed treat. Instead of forcing the mask onto a reluctant cat, you let the cat press their face in voluntarily to reach the food. Over 4–7 sessions, the mask becomes neutral — just another object that predicts something good. This is cooperative care training, the same principle veterinary behaviorists use for nail trims, injections, and oral exams.
Anti-Static Chamber
Standard plastic chambers carry a mild static charge that attracts aerosol medication particles to the walls — meaning less of each puff reaches the lungs. Neobay uses an anti-static polymer that keeps the mist in suspension long enough for a full breathing cycle. This is the same anti-static principle used in premium pediatric spacers, applied to a chamber scaled for feline tidal volume.
Two Mask Sizes Included
Cats are not one-size-fits-all. Every Neobay kit includes Small and Medium mask sizes so you can choose the one that sits most comfortably for your cat and supports a calmer, repeatable routine.
Latex-Free, BPA-Free Materials
Every component that touches your cat — mask, chamber, valve — is made from medical-grade, latex-free, BPA-free materials. No phthalates, no PVC. This matters because a cat's nose and mouth are in direct contact with the mask for several minutes daily over months or years of treatment.
How to Use & Clean
Simple enough to repeat every day.
1
Prepare the MDI. Remove the cap, shake 4-5 times, insert into the chamber back-piece.
2
Set the reward. Place a familiar treat in the Comfort Feeder.
3
Fit the mask. Gently apply the mask, ensuring a seal.
4
Deliver the medication. Press the MDI once. Watch the indicator, count 5-7 breaths.
Tip:
Let your cat explore the device before the first treatment. If they startle at the MDI sound, press it into the chamber before applying the mask.
1
Disassemble. Remove the backpiece, Comfort Feeder, and mask only.
2
Soak. Soak parts 15 minutes in lukewarm water with mild detergent.
3
Air dry. Shake out excess water, air dry vertically. Do not rub dry.
4
Reassemble. Reinstall components only when completely dry.
Maintenance:
Clean weekly. Replace after 12 months of continuous use.

Choosing the right spacer
Which spacer should I choose: 1-Pack or 2-Pack?
Most multi-cat homes or owners who want a backup spacer choose the 2-Pack — you save 19% per spacer vs. buying two 1-Packs, and pay less than one AeroKat. If you are new to inhaler therapy or only have one cat, the 1-Pack is the right entry point. Read the full comparison →
What's the difference between Green and Blue?
Only the color. Both Green and Blue spacers have identical features: Comfort Feeder, Flow Indicator, two mask sizes, anti-static chamber. Pick the one you and your cat prefer.
How much does a cat inhaler spacer cost?
A Neobay 1-Pack is $33.99 with free shipping. The 2-Pack is $54.99 ($27.49 per spacer). By comparison, the AeroKat is $61.95 for a single spacer. Neobay also offers Subscribe & Save — 15% off the first order and 10% off refills — available on the 1-Pack.
Is the Neobay spacer cheaper than AeroKat?
Yes. A Neobay 1-Pack is $33.99 vs. AeroKat at $61.95 — about 45% less. The 2-Pack brings the per-spacer cost down to $27.49, less than half the price of one AeroKat. Both devices use anti-static chambers and fit standard MDI inhalers.
Using the spacer
How do I train my cat to accept the spacer?
Start by leaving the mask near your cat's food bowl for a few days so it becomes a familiar object. Then load the Comfort Feeder with a small treat or wet food and let your cat voluntarily press their face into the mask to reach it — no forcing. Over 4–7 sessions, gradually introduce the chamber and, eventually, the actuated puff. Full 5-day training timeline →
How many breaths should my cat take through the spacer?
5–7 normal breaths. Watch the Flow Indicator — it moves with each inhale and exhale. If your cat pulls away before reaching 5 breaths, re-fit the mask gently and continue counting. The medication stays suspended in the anti-static chamber for several seconds, so a brief interruption does not waste the dose.
What if my cat won't keep the mask on?
This is the most common hurdle. Do not chase or restrain — it makes the next session harder. Try a higher-value treat in the Comfort Feeder (Churu, tuna paste), shorten the session to 1–2 breaths, and try again later in the day. Most cats accept the mask within a week of consistent short, positive sessions.
Can I use this without my vet knowing?
No. Neobay is a delivery device — it does not contain medication and does not replace a veterinary diagnosis. Inhaled medications like fluticasone require a prescription. Always follow your veterinarian's dosing instructions.
Cleaning & maintenance
How do I clean the spacer?
Disassemble the mask from the chamber. Wash both in warm water with mild dish soap, rinse thoroughly, and air-dry on a clean towel. Do not wipe the inside of the chamber with a cloth — that can create static and attract medication particles. Detailed cleaning guide →
How often should I clean it?
Rinse the mask with warm water after each use to remove saliva and food residue. Deep-clean the full device (chamber + mask + valve) once a week. If you notice visible residue or the Flow Indicator becomes sluggish, clean immediately.
When should I replace the spacer?
With weekly cleaning, a Neobay spacer typically lasts 12–18 months of daily use before the anti-static coating begins to degrade. Replace it if you notice reduced Flow Indicator movement, persistent medication smell even after cleaning, or visible wear on the mask cushion. A 2-Pack gives you a built-in replacement ready to go.
Can I share one spacer between two cats?
No. Each cat should have their own spacer — sharing can spread respiratory bacteria between cats and makes it impossible to track which cat received their dose. The 2-Pack is designed for multi-cat households for this reason.
Compatibility
Will this fit my cat's MDI inhaler?
Yes. Neobay fits Flovent, QVAR, Alvesco, and most standard metered-dose inhalers prescribed for feline lower airway disease. The MDI port accepts all standard HFA canisters with a 22 mm mouthpiece. If your vet prescribed a Diskus or Ellipta dry-powder inhaler, these do not fit any spacer — confirm the format with your vet.
Can I mix colors in the 2-Pack?
The 2-Pack ships as a single color (Green or Blue). If you need one of each, contact support after ordering and we will accommodate based on current stock.
Can I use a human spacer for my cat?
Technically yes — a pediatric spacer with a mask can deliver medication to a cat. But human spacers lack the anti-static chamber and feline-specific mask geometry that make daily use practical. Most cat owners who start with a human spacer switch to a purpose-built feline device within the first month. Read more →
Ordering & returns
Do I need a prescription to buy a spacer?
No. The spacer itself is a delivery device, not a medication, and can be purchased without a prescription. However, the MDI medications it delivers — such as fluticasone (Flovent) — do require a veterinary prescription.
Is the spacer covered by pet insurance?
Some pet insurance plans that cover durable medical equipment will reimburse a cat inhaler spacer. Check your policy for "durable medical equipment" or "prescription device" coverage. We provide an itemized receipt on request.
How fast is shipping?
Free standard shipping on all orders. Delivery typically takes 3–7 business days within the contiguous US. Tracking is emailed when the order ships.
