Black Zoo (1963)

Synopsis
This violent, gore-filled, effective horror tale by director Robert Gordon is about a totally wacko private zoo keeper, Michael Conrad (Michael Gough) whose literal worship of the animals he tends -- especially the cat species -- starkly contrasts with his cold-blooded disregard for human life. Conrad has a mute son Carl (Rod Lauren) with a simmering Oedipal hatred, and a wife who should have left him eons ago. Whenever Conrad gets miffed with anyone coming a little too close to his private affairs he simply feeds the hapless victim to the animals. It seems inevitable that if the animals do not get him, then the human species will. ~ Eleanor Mannikka, All Movie Guide
