Sneezy Kitty

So, for about a week now, Cocoa has been sneezing on and off.  I know exactly when and how it started.  I was grooming her, and she suddenly went into a sneezing fit.  I picked her up and found a pretty large tumbleweed of her fur on her nose lol.  Took it off and thought that was the end of it.

However, since then, she's been periodically letting out a sneeze here and there, daily.  Nothing else seems to be wrong at all.  She's eating, using the litter box, playing and is as cheerful and chatty as ever.  Maybe, just maybe, I remember her being out of sorts for a day prior to this all starting.

There is no mucus coming out when she sneezes that I can tell and, her eyes are clear.

Our other cat, Casper, has not shown any signs of illness, just for the record.

Because it seems kind of minor, we haven't whisked her off to the vet, however, now that I realize it's been a week, I'm wondering if I should?  Or if it's just something that might pass.  I know if it's a little cold, there really isn't much the vet can do for her anyway and since she's normal otherwise it seems kind of overkill.

Thoughts?

my cat has a sneezy cold, hes fine but he got my other cat sick now shes stuffy and weezy. remember just like humans virus act different in different people, so watch your other cat as well she may be ok, but if your other cat  he might not sneeze he might vomit, sleep more, snore(from mucus in nose or chest) or shiver or like my kitten atm be overly needy cause he doesn't feel well. also she may have an allergy to something in the house, cats respiratory system is very sensitive. so changing litter can cause allergies dust, pollen, ect

Litter is the same, however, and the other cat, nothing at all is different (thankfully).  But I will keep looking out for any other changes for sure.  Maybe it is allergies, We do vacuum and dust regularly but I do know the mold count has been high this past week here. Perhaps it has something to do with it. We haven't had her long enough to know her full history over the course of a year of weather.
