Ok so two days ago i picked up a rat from a person who found her in a small cage on the streets, its a little she rat but when i started preparing her cage so shed be nice, fed and comfortable and i wanted to pick her up i noticed her tummy was very hard and big and i also saw that her nipples were way bigger than a casual she-rat. Good thing that she adjusted to me real quick and shes really sweet, she just doesnt like loud noises so im very gentle with her. Maybe i can try to take a picture of her tummy? I also notice shes very calm and thats pretty odd since she was picked up from the streets all abandoned. I dont know how old she is but she looks young i think around 10 months maybe older.
