...these have been the words of my vet after several blood tests, swabs and xrays have returned negative.

I would appreciate anyones thoughts or advice about my cat. She first had symptoms 4-5 months ago when i noticed slight coughing when she ate. It then remained stable until about 6weeks later and she began sneezing. this progressed to sneezing blood and a wheezing sound to her breathing. We took her to the vets at this point and were given antibiotics which seemed to ease things, but as soon as these were stopped it came back with a vengence.
She now gulps when she swallows, has bad nasal congestion and the best way i can describe it is she sounds like Darth Vadar when she breathes. Its a real rasping sound from the back of the throat. She continues to sneeze blood too. Despite this she still wants to play and still wants to eat. Altho, she now won't touch any kind of tempting wet food. She had gone off food altogether last week, but with much persistance she is now eating dry food regularly which is a relief. The poor little mite has put up with having antibiotics daily for the past 6 weeks and metacam squirted into her throat. But alas, still no improvement in her symptoms.

If anyone has any thoughts or has heard of similar symptoms please please let me know!! My thanks in advance for any replies.
