Hi I have a cat who it about A year and a half old. I have had her since May When I got her she was sneezing and snotting yellow green junk. She had been this way two months before I got her and was on Baytril when I got her. She is still sneezing and snotting. She has been this way for 7 months now. She has been to 5 different vets and no one can figure out what is causing this. She has been on Baytril, Zithromax,lincomicin,and been given depomodrel steriord shots. Nothing helps. She has been tested for feline aids and feline lukiminia both neg. She has never ran a fever or had any other reasons to believe she is sick. I have 5 cats and she is the only one sick. I also had a cat I rescued until I could find it a home that had never had any shots and it did not get sick either. Does anyone have any ideas on what this could be and how to get rid of it. The last vet we went to has given up. She has been to all the vets in my area with no answers. Thanks for any advise you can offer.
