Should I have my 3-month old pygmies on a coccidia preventative, even if they've never had a problem with coccidia? The vet who did the fecal said there's no reason to be concerned with coccidia, since no abnormal amount was found in their fecal. Their poop has been normal for the most part. Every now and then I find a little clump, but not often. If I should have them on a preventative, what should I use?
