It has been said that most all rabbits carry coccidia to some degree. Only when under stress or extreme conditions of one kind or another does this become a problem.
Unsanitary conditions can also cause a significant increase of coccidia.
In my personal experience, I have found that the use of a coccidia medication on a regular basis, saves my animals from many stress-related health problems. Listed below are two of the most effective treatments for coccidia in the domestic rabbit. All dosages and treatment instructions were given to me by the late Dr. T. E. Reed. As Dr. Reed explained it to me, the first 5 days of giving only treated water kills all the mature coccidia, but not the immature ones. The final 5 days of giving only medicated water will rid the animal of those now mature coccidia that did not initially succumb.
