Hi there, I think my cat might be pregnant. She's only 10months old but her tummy seems to have got a little bit bigger and much firmer also I noticed her nipples have got quite big. She's very much a gentle and friendly cat, but lately she hasn't been going outside as much as she usually does and now follows me around the house. She much more prefers to lye around the house in the sun or snuggle up somewhere then be outside. What do you think?
