The first batch of babies are just opening their eyes. A few have them both eyes open already. Do you guys know if I can start to handle the two little ones that will be going to homes instead of being feeders? I want them to be used to people before they leave but I don't want the momma rat to kill them when I put them back in with her. How do I do this the right way? I want them to be safe. PS They were born Sept 20.
