So I decided to start breeding my own rats. the male is a dumbo, female is a hooded. I dont need to many rats as I have 2 small boas but I figured I'd break even on the money, and gain a wealth of experience doing it myself. I plan on adding a couple of more boids to my collection next year, so I might as well start with the trial and error now. Oh and my kids wanted some pet hamsters, instead they will each get to raise a baby rat when they are born .

Quick question, besides seeing the rats mating, how do you know if they have?
