Age rats start breeding?

[DeadlyDesires]

So one of my females passed away today, im not sure what happened, she had blood coming out of her back end and her nose when i found her, i cleaned the whole cage with bleach and water and im hoping whatever it was its not contagious considering i feed the pups to my savannah. So, my question is what age do rats start breeding? i have 2 females put aside with very cool markings that i would love to breed they are about the size of small/medium rats currently. Thanks :D

Rats can breed about 2 months of age. Usually once they become Mediums (85-174g) they're sexually mature but IMO it's better to wait until they become Larges over 200g. This way they're more able to have bigger litters with ferwer problems.
