But considering the poor accuracy (ref) of veterinary
fecal floatation methods when parasite numbers are few or moderate, it is much safer to just keep your pet on a monthly heartworm or flea preventative that also prevents intestinal parasites.
Coccidia are easy to find using standard
fecal floatation methods for fecal exams and are often present in sufficient numbers to show up if a small amount of stool is smeared on a glass slide, mixed with a small amount of saline and examined.
