I found some coccidia (parasitic, apicomplexan protozoa) in the stool of a cat with chronic diarrhea of ~8 years duration. We recommended testing the other cat in the household, and he was also infected.

Cystoisospora felis (aka., feline coccidia) unsporulated oocyst found in the fecal flotation of a cat with chronic diarrhea, 400x magnification, 20 μm scale bar:
