Okay so my one cat is very loving and very affectionate. He loves sleeping next to me in bed and always follows me everywhere. I'm now roughly 19 weeks pregnant and he's been acting differently. He no longer sleeps next to me and likes to sleep either in my closet or at my feet. He still seems the same other than that. Maybe a little less affectionate as well. Is this a normal thing that happens to a cat when being pregnant? I just worry because I had another cat who passed away last year and he hid in the closet towards the end of his life.
