Why is my senior cat still coughing after a year on medication?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 13 lbs

I have a cat that is around 12 years old that looks and acts healthy except he starts coughing. The vet put him on dycycoline a little over a year ago, every other day. Is their anything that would clear it up? Thank you Janet

Poor Chip! If the doxycycline is not clearing up the coughing after a year, it's not likely to help much at this point. Don't stop any medication however without consulting your veterinarian. Chip needs to have a radiograph to check for signs of asthma or something in the chest pushing on the trachea. Heartworms can also cause coughing. They can be tricky to find but a blood test may help. I recommend to have Chip re-evaluated and these tests run if they have not already been done. It's important to figure out the cause. I hope this helps.
