> Does this mean that my PIR motion sensor on my little robot can be used not just to detect motion, but as well to find warm things?  So I could put it on a servo and it could hunt down my cat?

My favorite use is to put two of them on the back of the bot at the rear
corners, each angled a bit out. They can be used to detect a child and
run away from them. Makes for fun all around. My next version I'm going
to add some more intelligence so that it knows some good hiding places
and when to go silent.
