First off here's a wonderful article on "red tears" just for you to read up on the whole scientific deal with it (I love this kinda stuff so bear with me).

Way back when we first got rats I did see more porphyrin production and it is more obviously seen on light/white rats due to coat color. We found with adjustments in our husbandry...bigger enclosures, more ventilation, replacing pine with aspen, less rats per cage, sorting rats so that really dominant ones aren't picking on smaller/weaker ones....we don't see it any longer in our colony. If you see it very occasionally it's not such a big deal, see it a lot it is something to be concerned about. As far as I'm aware (not a vet remember), it is an indicator of a stressed or ill rat so even a bit of it is a heads up to look at your rats setup or general health. It is not a breeding issue, it's a husbandry or health issue (unless the health issue precludes that adult from being a productive breeder of course or the underlying health issue is from a genetic defect).

The male with the sneezes may be a myco flareup or it could be a simple reaction to bedding. Since your female is showing stress reactions, perhaps the male is also reacting to the bedding. That would be my first step before considering any permanent solution...a bedding change and seperate the rats so they don't compete with each other and don't re-mate until you know what you wish to do or what you are dealing with. Give them a solid week, maybe even two, of that and see if you are getting any improvement.

Sound reasonable? Oh btw if you don't usually put them on aspen, pet store aspen is ridiculously overpriced....WalMart is way cheaper for aspen...or if you have a TSC farm supply store they have killer prices on HUGE bags of aspen.
