My 4 year old cat started with a cough that sounded like a toddler coughing 29-30 days ago. Then it progressed into a hacking cough. 9-10 days later I noticed that she wasn't eating. She also had the following symptoms, mucus from the nose, teary eyes, and lots of sneezing. The first vet I took her only tested her for FIV which came back positive and FELV which tested back negative. He made it seem like it was a death sentence and only gave me vitamins. The next day I took her to another vet for a second opinion. They put her on Convenia, 2 doses 4 days apart of Enrofloxacin, Yaten Caseina once a week for 3 weeks. Nebulization every 6 hours, and prednisolone. I saw a bit of improvement after enrofloxacin and even began eating on her own the day after. But then her health kept declining. I went for another visit and they put her on Sinvirax for 5 days and vitamins. I'm on the 3rd day of sinvirax and I don't see improvement. There is no longer any coughing and less sneezing but there are 2 or 3 sores on her mouth, still not eating on her own, mucus on her eyes, nose, and drooling. Should I look for a third opinion? I'm currently in Central America and I'm in the process of relocating her to the states but I don't think she will be allowed to travel like that.
