2018 Breeding Plans

Babies get sexed at 4wks old then I will take pictures and post them in the nursery.


I will only breed a couple of litters at a time. No other litters will be bred until the others go home. This is to ensure I do not end up with to many rats. Some pairs may be pushed back depending on how fast babies get adopted.
