Thanks guys. I got him from Petco. I've noticed for the past few days I've had him he sneezes a lot, which I think is a sign of respiratory illness. I need his future babies as feeders so I don't want to have to keep breeding only to find out I have to scrap him and his offspring if he does carry MC. As much as I feel like a crappy person I'm going to call Petco today and explain the situation (needing him to breed for feeders excluded). This Saturday I only work one job so my boyfriend and I plan on a trip to the East Bay Vivarium and I'll pick out some rats there.

Thanks for the help! I very much appreciate it.
