hi and welcome....i hope i can help, antibiotics aren't really useful for a URI unless there is absolute certainty that an infection is present, its usually NOT...therefore the best thing you can do for your kitty with these ongoing upper respiratory issues is to support her immune system. this is one of the very best products to use. you can buy at a good human health/vitamin supply. I urge you to buy this brand b/c it is one that is safe for use in cats...no ingredients such as soy, wheat, corn, sugar, salt, preservatives that are all harmful.
use 500mg for first week than 250 mg for maintenance.
and this product in this brand for relief from the sneezing..and discharge....is an excellent product for cats with URI..
use 1 opened capsule mixed with food until symptoms cease.
these 2 supplements are very inexpensive. if you order from iherb quote this code and you will recieve $4 off and that will cover your shipping. they are located in CA. and a very reputable company.
I urge you to use these. I don't think any antibiotics are required, unless symptoms persist after trying both these supplements aft a week......good luck and keep us posted.
sorry forgot to add the code # SED597
