Hi...my cat frequently sneezes..shes been to the vet 3 times...they have ran blood test..all normal..fhv..fiv all negative..she was tested when she was a kitten...could it just be allergies? I switched to a dust free litter..my home is fairly clean...as we have it cleaned professionally every other week. Don't know what else to do for her. Thank you...i should mention she does n't have any eye or nose discharge..vet chalked it up to feline herpes and with the occasional flare-ups

Hello. It could be allergies, but most likely this is a flare up of the feline herpes virus. If her symptoms are relatively mild, then I would not be too concerned. You could try her on the amino acid L-lysine, many forms are available at most pet retailers, but for the most part the results of using this has been unimpressive. You could also start her on an immune boosting probiotic. Again, the results of using this are mixed, but it is certainly not harmful. The one I recommend is Purina's FortiFlora. Hope if you decide to do these you see some decrease in her sneezing. Thanks for using Petco Pet Education Center, formerly Petcoach.
