Oscar sneezing :(

My poor Oscar has been sneezing. His nose is slightly runny and he's a little less active but still eating drinking and all that good stuff. I remember last year he had a doozy of an URI and had to go in for antibiotics. I think he might be fighting it off as he isn't getting any sicker like he did last time. I hope he doesn't get any worse as I am snowed in as we had a bad snow and ice storm this last week and my car can't get out of my carport without spinning my wheels. (Shoulda got the snow tires). Anyways, any advice on helping him fight this thing off? Just my luck he should get sick during a snowstorm. I'm a native California girl and still not used to this real winter weather lol.

Thanks guys, he is still doing ok. He will have a sneezing fit and then be ok for a few hours. He isn't as stuffed up as he was last year. I had to use saline drops on him last year as he couldn't breath out his nose very well. I'm thinking he is fighting it off better this year. I did give him some lysine that I had left over from last time. He was sleeping in the closet on the suitcases which he does if he wants to be left alone, but he came out to eat a little while ago. He hung out while I took a hot shower and that helped him a lot.  I wonder if the different vaccine is helping at all. He got the modified live this time instead of the killed virus, and he actually got sick after the vaccine. I was upset when I got him the vaccine but am thinking that it might have made this episode of URI alot more mild.
