My girl fiona has undergone a big personality change in the last couple days. Shes keeping more to herself, isn't as playful or affectionate as she used to be, and actually runs and hides from me which shes never done before. She's about 10 weeks old and I've had her and her sister for about 2 weeks. I was holding them both today and noticed that Fionas tummy is bigger, and firmer then Callies and it also feels a tad lumpy. Also her nipples are visible, not protruding, but visible, her sister callie also has a white belly and u can't see her nipples at all. Is there a chance shes pregnant? she's not nesting at all. And wasn't with any males when I got her, but I adopted them from someones "ooops" litter So I don't know if she was with males before hand. Thank you!
