Pets sense the baby.

The day before I figured out I was pregnant, my cat had laid on my stomach all night long. And pretty much every night since, that's her favorite spot to lay is on my stomach, or right on my lap. 
Also the other day, my mothers chihuahua had curled up right beside my stomach an laid her head on my small bump. 
I think it's amazing how animals can sense such things. 
Is anyone else's animals doing peculiar things? Or things they haven't done before? How is your animals sensing the pregnancy??  Animals are such amazing and sweet creatures. I can't wait to see what they'll be like when the baby finally arrives here.
