Anthrozoologist Hal Herzog's new book explores our conflicted feelings about other species. He shares some thoughts:

PET OWNERS AREN'T ALWAYS HEALTHIER

People believe pets are miracle workers, and for certain people there seem to be health benefits. But some studies show pet owners are worse off.

OWNERS DO LOOK LIKE THEIR DOGS

ABUSING ANIMALS ISN'T JUST FOR FUTURE SERIAL KILLERS

About 30 percent of male college students say they abused animals as kids.

VEGETARIANS HAVE MORE EATING DISORDERS

Vegetarian women are about four times as likely to be bulimic.
