Twelve stray cats age above 1 year-old, both sexes, were used in this experiment. They were equally divided in to 3 groups: group 1 a control group, group 2 and 3 were experimentally infected with Trypanosoma evansi subcutanously and orally. Parasitaemia in cats group 2 and 3 were detected on day 2-4 and day 5 respectively. The obvious clinical signs of infected cats were intermittent fever, dullness, anorexia emaciation, fur losses, pale mucous membrane, conjunctivitis, opacity of cornea and lens, subcutaneous edema of head and limbs, abortion, convulsion and death. Haematological and serological analysis revealed that haematocrit and glucose values were lower than normal while other values fell in normal ranges. Postmortem findings were pale muscle bundles, congestion and enlargement of liver and spleen, lung emphysema and congestion and pericardial cavity filled with exudation fluid. Also, marked changes of spleen, liver, kidney, lung and heart were observed microscopically.
