Brown and white Norway female rat. I rescued her moma from someone who had bought her to feed to a snake but the snake wasn't eating here. So through a friend, I was given her. About two weeks later, she had nine babies that included Cosmo. I then had 10 pet rats! As soon as I could tell, I quickly seperated the males and females.
Cosmo was my little "Fraidy Rat". She wasn't as interested in humans as her siblings. She would shy away more when the cage was opened.
