I have no clue but every time I've been pregnant I have hated all animals around me!!! Like they are just so freaking annoying!! I loved my parents dog and stuff. He's probably the only one I don't mind, but my in-laws dog and cats! I HATE! I HATEDDDDDD the cats when I lived here and was pregnant with my first baby. I didn't want them in the room EVER. I didn't want them on the bed or my daughters things. UGH. I just hate that I'm like this but I can't help it!! Lol
