How do you know your cat have asthma?

He was coughing a lot and lost almost 3 lbs. When I took him to the vet they said he have an infection in his lungs and gave him antibiotics. Three weeks later they took more xrays and said it have not cleared up much so it must be asthma. Now he is on both an antibiotic and steroids. I have lost confidence in my vet. I feel approaching they are just guessing. Has anyone had a similar situation? What do you suggest?
Curiosity. How mature can a feminine cat...
Answers:    Hi within... in all honesty it is quite difficult to present a diagnosis as to what your cat may have. Symptoms of various respiratory disorders can mimic one another sometimes even confusing the most experienced medical professionals. Upper respiratory infections can also discovered to be part of the elegant herpesvirus as well as asthma.

Here are some websites that hopefully help you determine what you are witnessing with your cat's strength.
