I have a pitt bull and an .American bulldog and they definately knew I was pregnant.
I made it a
point to have them lick my huge belly and repeat 'baby in the belly' over and over.
My belly got huuuuge and they used to *watch* .Nana move around in there! It was insane!
Now they have a new best friend!!! They love .Nana soo much!!!!
When they first met, she was only known as "baby in the belly"!!
I think dogs would know more than kitties though. I don't think kitties care enough...At least mine doesn't....She's very unsocial to others.
