I had a shy cat that came out when we had a couple of friends over. She walked over everyone on the couch and decided to plunk herself on the pregnant lady's lap. This was completely out of character for her. The lady wasn't even a cat lover (usually cats know this and stay away from non-cat people).
I have a 23 lb male rescue cat right now who can't get enough snuggles. I don't know if it's because I'm pregnant or what but oh my goodness, I love you too but could use some sleep please! I love animals, they're SO smart, we hardly give them credit!
