Hi Guys, my two blue female rats (just turned a year old) have had the sniffles for about a month now. We've taken both to the vets and they were prescribed a course of baytril and some anti inflammatory drops. They responded well and by the end of the course, they'd recovered. We went away for a 5 days and a friend looked after them, when we returned they were sneezing and sniffling again. Took them to the vets got another course of antibiotics and we've just finished it. But they're still sneezing and sniffling. Could this be a result of some kind of allergy? I know blues are very susceptible to myco and respiratory problems but apart from this they're really healthy and active. Any advice would be appreciated. Not sure if we should take them back to the vets again or not?
