What Happens If a Cat’s Trichomoniasis Is Left Untreated?

A cat with trichomoniasis usually has soft stool, diarrhea, or even bloody stool. If untreated, the parasites rarely clear on their own and multiply, draining nutrition, damaging the gut, and causing weight loss, anemia, dull coat, drowsiness, and frequent vomiting and diarrhea.

If you choose not to treat it, feed a prescription gastrointestinal diet to ensure adequate nutrition, and avoid raw fish or meat that could introduce more parasites.
