Hey guys

So I recently picked up two breeder female rats (one happened to be pregnant) from a pet store, in the hopes of starting a small colony, and have a concern.. I'm noticing that one female is sneezing quite a bit. It seems to happen most often when I'm around/attempting to interact with them, so I wondered if maybe it was stress related.. but at the same time I don't want to risk it being something contagious that spreads to my pet rats. They came from the same cage, so they've been together for a while now, however only one is sneezing and the other isn't. Should I separate the two? Or euthanize the sneezer just incase? Or do I spare the risk, euthanize both and start over from a different store? Advice is appreciated
