We've had one that was hunting most of the time. It was an old no one and everyone's cat. He was outside all the time and got invited inside during the worst cold during the winter. He also managed to get them effectively, despite having only one good eye. He would bring the voles, made sure we saw how good hunter he is and then eat them whole, leaving just bile which he surgically removed. He was the only cat that never ran from my dog and they were friends from the beginning when she came. She never chased him (he would not run, he would rather just use gentle boxing gloves with no claws and fight), but they could stare at each other for hours.

She still does the same staring game with cats that don't feel like running. She plays catch with other cats and if they run, she loves to chase them even more. That way, there are more voles for her, because cats usually keep a distance.
Aaah, rest in peace mr. cat
