A Pet's point of view

I’ve always wondered what it’s like from a pet’s perspective of things.   Animals seem to view life really differently than human beings.  They are really simple creatures compared to humans. I’ve always pondered on these specific questions:  How do they feel when they first interact with people?  What is it like being in a house for them?  How do they feel even living with human beings?  It’s always been something that’s fascinated me.  If there was a movie on an animal’s point of view, that would be really interesting.
