My three-year-old cat suddenly started sneezing a lot last night about this time. Prior to that, there was nothing like this at all. She sneezed so much overnight that she kept me up most of the night since she sleeps with me. She has no other symptoms of illness. I was concerned that she might have gotten something stuck up her nose so I got her into the vet early this afternoon. The vet looked up her nose and didn't see anything. She examined her and saw nothing that made her suspect some sort of infectious illness. She asked me about whether she gets stressed. She offered Cerenia nose drops. She said it was anti-nausea medication, but that it has the side effect of helping with sneezing so that's why she gave it. She also recommended Viralys supplement for immune system support. She is still sneezing this evening, but I haven't given either of the items yet. The vet is rather inexperienced and young - it's a larger office with five vets and I always seem to get offered her. I find myself wondering if something is still up there and the vet just didn't see it. Has anyone else given Cerenia nose drops for sneezing? Or has anyone else tried Viralys (it looks like an L-Lysine supplement for cats)?
