feeder mice and rats parasites

They can carry parasites, but it's really not that common. I fed live rodents from pet stores for several years before I switched to f/t and never had a problem. As long as the store seems to keep them in good conditions you should be fine. You could also always start breeding your own if you're that worried, or try to switch to frozen and order them online from a reputable provider.

Only time to worry about parasites on rodents is during Flea Season.
