Is that a sneeze?

I heard a sneeze! Why did Suki sneeze? I want to know! Wheek! [Suki seemed very well-cared for and healthy and had been for a month prior to coming here. She sneezed quietly a couple of times since she was with Dolly and Kira. Not sure if adjusting to a new environment and having Kira go after her briefly during bonding caused her resistance to be down or if it was all along and it did not surface until after the bonding session. It's possible that it might be the hay since part of it was dusty. I shook the dust out and will order some bluegrass from Kleemama's to see if that helps. Even though there are no other signs of a respiratory illness I will give Bactrim and liquid Vitamin C preventatively for a week in case it is needed. Very young/small guinea pigs can go downhill very quickly and I do not have access to a vet until next Saturday at the earliest. The attached photo shows Suki in her larger cage this morning with her cage pad and hut made by Jen and tunnel made by Windespirit. She loved running back and forth between the tunnel and hut!
