Tritrichomonas foetus is an emerging intestinal parasite of cats, causing chronic large bowel diarrhea. In cattle, this protozoan parasite is a sexually transmitted pathogen, infecting the uterus of cows and the preputial cavity and urethral orifice of bulls. In this case report, the first feline record of T. foetus infection of the uterus is described in a 17-month old Exotic Shorthair queen in Norway with pyometra. This queen had no history of diarrhea. Three other cats in the cattery were diagnosed with T. foetus infection using PCR on fecal samples: a 4.5-year old Persian male with intermittent diarrhea, a 22-month old male Exotic Shorthair with normal feces, and a 2.5-year old female Persian with normal feces. Interestingly, T. foetus has never been identified in cattle in Norway, although it is a reportable disease.
