What Is a Cat Inhaler Spacer?
A cat inhaler spacer is a chamber-and-mask accessory that connects to a compatible metered-dose inhaler (MDI). Neobay includes a visible breath indicator, two mask sizes and a treat-guided Comfort Feeder to help cats practise accepting the mask. The inhaler and medication are not included; follow your veterinarian's instructions for fit, technique and use.
A cat inhaler spacer (also called a feline aerosol chamber) is a non-medicated chamber-and-mask accessory used with a compatible inhaler prescribed by a veterinarian. It does not contain medication or replace veterinary guidance. Neobay includes a treat-guided Comfort Feeder to help cats practise accepting the mask at home.
Ask your veterinarian to check technique if your cat takes shallow breaths, resists the mask or seems uncomfortable during the routine.
How a Cat Spacer Fits into a Vet-Directed Routine
A veterinarian can advise whether an inhaler is appropriate for your cat and show you how to use a compatible spacer. A chamber and mask help you follow that prescribed routine, while the Breath Indicator provides a visible breathing cue. The spacer does not contain medication, confirm the dose your cat received, or replace veterinary follow-up. Ask your veterinarian to check the inhaler fit, mask placement and technique if your cat resists the mask or symptoms change.
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 7-10 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?
Choose a Single pack for one planned routine. Choose a Double pack only when the second chamber has a clear purpose, such as another cat, a second location or a planned backup. Check the live product page for the current local price and pack options.
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?
Prices vary by market, selected colour, pack size and checkout terms. Open the product page for your market and confirm the displayed price, delivery and return information before ordering.
Is the Neobay spacer cheaper than AeroKat?
A current price alone does not establish which option is right for every cat or household. Compare the complete kit, the selected pack, delivery, returns and the veterinarian-prescribed routine before deciding.
Using the spacer
How do I train my cat to accept the spacer?
Start with short, voluntary familiarisation using a familiar treat in the Comfort Feeder if appropriate for your cat. Do not chase or force the mask. Follow the plan from the veterinarian who prescribed the inhaler, and use the step-by-step training guide for a gradual practice routine.
How many breaths should my cat take through the spacer?
Follow the breath count and technique supplied by the veterinarian who prescribed the inhaler. The Visual Flow Indicator is a visible cue during use, but it does not replace veterinary instruction or confirm a full dose on its own.
What if my cat won't keep the mask on?
Do not chase or restrain your cat. Use short, voluntary practice sessions and a familiar treat in the Comfort Feeder where appropriate. If the routine remains difficult, ask the veterinarian caring for your cat for technique guidance.
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?
Delivery availability, timing and charges depend on your market and the selected checkout option. Review the current delivery information at checkout before placing an order.
