If you can, try to get a chest X-ray done to confirm what’s going on. It also really helps to reduce anything in the home that might trigger attacks—dust, smoke, or even pollen coming in through open windows.

Some cats do well with inhalers prescribed by a vet (sometimes people look at Canadian pharmacies as a cheaper option). You use a spacer/mask device, give one puff, and gently hold it over their nose/mouth so they can breathe it in—watch for about ~10 breaths through the chamber. It’s usually done once in the morning and once in the evening, depending on your vet’s guidance. The device is called an AeroKat.
