The species in the intestine of the cat is not the same as that found in the mouth of the cat and other animals. The parasite from the intestine of the cat has been considered a separate species by some authors (Brumpt, 1925; Cunha and Muniz, 1922); however, others have felt that it is the same species found in man and other animals ,such as the dog. The organism in the feces of humans has been shown capable of infecting cats that are orally inoculated with trophozoites (Kessel, 1926; Hegner &amp; Eskridge, 1935). Reports of trichomoniasis from cats have been reported from the United States (Jordan, 1956; Hegner &amp; Eskridge, 1935, Hitchcock, 1953; Visco et al., 1978), Europe (Brumpt, 1925; Simic, 1932; Wagner and Hees, 1935), South America (da Cunha and Muniz, 1922), and China (Kessel, 1926 &amp; 1928). It does not appear that this organism causes disease in the cat, rather being a commensal that is found in feces of cats with diarrhea due to other causes.</span></span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-family: 'Times New Roman', serif;"><span style="font-size: medium;"><b>REFERENCES:</b></span></span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-family: 'Times New Roman', serif;"><span style="font-size: medium;">Brumpt E. 1925.
