Heavy infestation of cat flea, Ctenocephalides felis, with itching sense was found in 9 dairy rearing calves kept in a paddock with saw dust floor mat. Four calves showed mild to moderate anemia. After treatment for one month with organo-phosphoric insecticide of carbamates, infesting fleas were remarkably decreased and simultaneous recovery from anemia was observed. However, fleas were again found on severed other new calves 3 days after their introduction to that paddock, suggesting that treatment was insufficient
