Hello, my old cat has had trouble breathing through her nose to the point she only has a tiny spot left open to breath through, right now she mostly breaths through her mouth. The pet doctor here thought it was an infection in the lungs and has gave me doxycline 50mg 8 tablets. I visited another doctor and said she thinks it could be a tumor in the nose because there is no snot leaking or coming out, so she gave her pretnizon, but she only took 2 dxyc, can I continue or not due to the pretnizon?
