If Milo has an occasional brief sneeze, is it something to worry about?

Since Monday I have been noticing that he is sneezing .. once every few hours or so, at least when I am in earshot. There is a small spray of clear droplets from his nostrils. ( I have had some allergy-relating sneezing also.)

Other than that, he is relaxed, calm, content, and continues to alternate frenzied mad dashes with nap, pre-nap naps and post-nap naps.

He is drinking, eating and pooping normally. And he seems to still spring onto high surfaces with little effort, is happy to attack my hair scrunchies, and is manifesting almost no aggressive behavior. And he is hunting normally as well. Should I be concerned?
