Thank you all for your kind words! I saw a new vet this afternoon and he said that Poupette has mild asthma and unless she rejects some kind of a mucus or has problems to breathe after a cough, which she doesn't, it is better to let nature play its role. So coughing two or three times a day is not alarming. If she had problems to breathe, he would give her anti-inflammatory pills. Ah... he said also that it would be better... for me, to quit smoking . Smoke is not good for a cat too! It was my first experience in a forum, and I must say that it was very positive! Again, thank you all!
