Thanks Jess - I don't know if I'm in a heartworm area or not
NY state would be an unlikely but possible area for heartworm. There are sometimes certain changes to the lungs and vessels that indicate heartworm on x-ray, but this can't be counted on.
(would that show up on x-ray? vet said Sam's heart looked great!).
Unfortunately feline heart disease cannot be diagnosed (or excluded) on x-ray :sad:
I will talk to the vet about getting a rescue inhaler, but he really talked as if there was a good chance that Sam would only need the steroid shots (at what interval we don't yet know, depends on how he does). I don't want to just brush off the asthma, but that is what the vet said, and Sam only coughs occaisionally.
A rescue inhaler is for a bad asthma attack. Just as people with asthma have a regular medication for everyday, they also carry with them an inhaler in case of attack. You won't know that Sam needs it until he needs it (can't stop coughing, is struggling for air). ALbuterol (the inhaler) is pretty cheap, and you can get an AeroKat online. (That is the delivery chamber for the inhaler. Cats won't suck on the end of the inhaler like humans do.) Check out Fritzthebrave.com for more info, picture, and links.
I would not depend on occasional steroids shots for asthma -- inhaled medication is the way to go as you avoid the risks associated with systemic steroid use.
Does your cat have access to outside? I would run some more tests if he were my cat, but esp. if he went outside. These would include blood tests for toxoplasmosis and cryptococcus, a regular fecal test, and a Baermann fecal test. (This tests for worms that could go through the lungs.) The Baermann is expensive, IIRC, so you could also just deworm him with a broad-spectrum dewormer like Panacur. It's likely that all these tests would be negative but they are done to rule out anything curable before treating a chronic disease for a lifetime.
You could also test for heartworm antibodies and antigen. Heartworm is not treatable in cats, though, so if $ is a concern, you may want to ditch this one (although HW test is not too pricey, if I remember correctly).
The reason I kept bringing it up to the vet was because we lost one cat to hypertrophic cardiomyopathy and I was told at that time that one symptom I might have missed was a cough.
Hmm coughing is a VERY rare sign of heart disease in cats. In dogs, yes, but in cats, not really. Coughing is associated with respiratory disease.
