Yea the current 5 females i have my male has been through them all and each one has had at least 2 litters for me.

Except the youngest female in all of the pics, she hasnt been bred yet. Ill make sure i do not breed her to any high white males, Even tho it seems both of my males are not high whites anyways lol!

Seems like there are A LOT to rat genetics. Lucky me to have some "risky" rats to start out with huh
