Yes, I ran every test the vets suggested, including asthma and allergy tests. They say it's this bacteria "mycoplasma felis," and they keep giving me antibiotics to get rid of it, but it was still coming back every winter. Now it seems like it's coming back every couple of months, and well, she's actually wrapping up her latest stint of antibiotics tomorrow, and she was wheezing last night, so I'm just hoping it won't go right back to being bad when she's off them.
