There are 5 girls and 7 boys. The babies were born on Christmas Eve. The mom was rescued from a shelter. There was an apparent oops and she had unplanned babies. They need to go to responsible homes. They are NOT feeder rats. The babies are very sweet and playful and healthy eaters. If you have never had pet rats before you will need to do your homework first. They are like mini cats and like any animal need to be cleaned, loved, fed and well cared for. Young children must be supervised around them or ANY animal.
