A survey of the endoparasites of 100 stray cats in central Utah was conducted. Each cat was euthanized, and the entire alimentary tract, gall bladder, bile duct, heart, respiratory and excretory systems were excised and examined for endoparasites. Fecal samples were examined by a sugar flotation technique. Parasites identified and number of cats infected were: Isospora felis 5; I. rivolta, 4; Dipylidium caninum, 1; Hydatigera taeniaformis, 10; Toxocara mystax, 43; and Physaloptera sp., 2. One ectoparasite, Cheyletiella parasitivorax, was identified in the feces of 4 cats. Dipylidium caninum and T. mystax are known to cause accidental infection in humans and could represent potential public health hazards in Utah.
