title: Breeding laboratory cats during artificially induced estrus.
abstract: Mature female cats of known reproductive history were randomly divided into groups for natural breeding or mating following hormonal induction of estrus. Treatment with a single injection of 100 international units of pregnant mares' serum followed in 7 days by 50 international units of human chorionic gonadotropin produced results comparable to natural breeding. Daily injections of pregnant mares' serum (300-500 international units total) resulted in fewer successful pregnancies and adversely affected the ability of kittens to survive to weaning.
