My males don't eat as often as the females nor are they as large as the females but they do eat regularly and will get some size if they live long enough.

I've got one male that is at least 17 years old that is only about 20". He eats rat pups, not as often or as many as the girls, but he's good for one or two fatties every couple of weeks from April to October with a few missed weeks when he's "courting."
