Hi! So my situation is one week ago I got two sweet little girls (Ben and gally) from the shelter. Both we moderately socialized but gally was the friendlier. From the beginning she liked to snuggle and just chill on my shoulder or with me on the couch. Two days ago she decided not to be held at all. She squeaks when you try and even bites. With my limited handling of her she seems to have suddenly ballooned in weight. Her sister is long and sleek. She is a little round. They are 9 weeks old. Her nipples are visible not extremely visible but noticeable. She hides in her box most of the day except to dart out for food and a quick drink. My concern is not knowing if she is pregnant or sick. She is eating. She is drinking. She is just antisocial. Does this sound pregnant or sick? And if she is pregnant what do I need to do for her?
