My cat eats wildlife everyday?

my cat eats wildlife everyday. it started with lizards then squirrels, birds, mice, rabbits, gophers, snakes, and he comes in to eat his regular food. he is incredibly healthy. at first we thought it was for fun for him, then we actually seen him eating the animals. is this bad for my cat? is this bad for the other animals in my household? i have 2 other cats and 3 chihuahuas. how would i stop him from eating these?
