Hello XXXXXXXX,
How old is she?
Does she have any nasal drainage or sneezing?
How is her appetite?
Is she still active?
Thank you Rick.
It sounds like she has a respiratory infection. The couging is a concern as that can indicate possible bronchitis or pneumonia. You are going to have to take he back to the vet and have the vet ascult het lungs and possibly take chest x rays.
She could also have feline asthma. http://www.veterinarypartner.com/Content.plx?P=A&&A=665 This is diagnosed with chest xrays and clinical signs. Sometimes there is a needs to do more advances diagnostics such as examining fluid from the trachea.
I would rule out these two diseases first. She could also have heartworms or lungworms but that is not as likely.
