Yes! My dog constantly walks over me, pushes her head against me or tries to lay in my lap. Mind you she's a German Shepard mix so she isn't little lol. If I leave the room she chases after me and I wake up in the morning to find her asleep cuddling against me
My cats have def been acting different. My girl who was kinda antisocial follows me around the house all day and wants cuddles on the couch, and my male was cuddling me on the couch the other night with his paw on the top of my bump and his head resting on it. My husband took a pic and posted it on Facebook saying I think he knows.. lol my friend has 3 cats and has also been saying how dif they r since she's preg and were even more friendly towards me when i was over the other day.
