A couple of years ago my cat (he'll be nine in March) was diagnosed with feline asthma. He has never improved with medication prescribed for asthma and they have tried several. Recently he has gotten so bad that I began to think that maybe it was time to consider having him put down. In desperation I searched the internet for any other possible solutions and found an article about feline asthma often being misdiagnosed. Turns out that sometimes, it is just a plain low grade upper respiratory infection and responds well to antibiotics. I obtained some amoxycillin for Ricky and have been treating him for the past three days. I cannot believe the dramatic improvement!! He is not wheezing nearly as bad, not coughing and hacking...and he's even acting frisky!
