Three 3-day-old kittens were inoculated subcutaneously and orally with Neospora caninum tachyzoites. A littermate and the queen were not inoculated with N. caninum and served as controls. Kitten 1 died between 14 and 16 days postinoculation (DPI) and was eaten by the mother. Kitten 2 died 17 DPI and kitten 3 was euthanized 29 DPI in a moribund condition. The control littermate and the dam remained healthy. Granulomatous skeletal myositis and nonsuppurative encephalomyelitis were the main lesions and were associated with numerous N. caninum tachyzoites in kittens 2 and 3. Cysts were found in kitten 3. Oocysts were not found in any cats. Neither lesions nor parasites were found in control cats.
