Hello I am just wondering why my 7 week pregnant kitty is barely showing its her first litter and it was an acident my kids let her out in heat before we could get her fixed she isn't that big and I've only seen on side bludge out at a time she's healthy and eating good I bought a fetal Doppler and listened to her belly and only heard one heartbeat could she only have one kitten in her belly she was very thin before but vet said she was healthy why is she not really showing I'll include a picture taken yesterday
