i got two baby girls from a rattery about 15 days ago and they were about 6 weeks old. recently one is becoming a lotttt bigger than my other girl. They werent housed with male rats but im not sure if they were close by or if any accidents occurred, but to me it looks and seems like shes pregnant.Shes very pear shaped and eats/hoards a lot. Shes shyer than my other female and doesnt like being handled as much. Please lmk what you guys think!!
