    Trouble sexing wean rats
    I did google on how to sex young rats, and found multiple great thread about this top. But i'm still having a hard time sexing them when i try to wean them off and put them into grow up tubs. Any tips about how i can for sure tell their sex?:bow:

    Females have nipples. Males do not. This is easily seen on their lower bellies.
    Their genital to anal distance is also different. Females have a very short distance between the vaginal opening and anal opening. The male has a further distance between the penis and anus. Not to mention his scrotal sac will drop at around 4-5 weeks of age. So you could always just wait for that to happen before splitting the litter.


    Around 3 weeks of age.

    ok so for the distance, do you just eye ball it? or just compare with other rats with the same age. I find this to be pretty tricky.

    What Satomi said. You will get an eye, and get used to what you are seeing. My 10 year old can now sex rats.

    Yes, I eyeball the distance. It's something that you learn with experience. So keep looking and comparing your rats. It will be easier with time.
    And IDing a male is a lot easier when their balls have dropped. Females are a lot easier as pinks or fuzzies because their nipples are pretty prominent. It's the ages of 3-4 weeks that can be tricky.

    In my head every time I sex a rat i still subconsciously ask myself if that's enough room for balls to grow later. I don't know if that's crude or not to say, but I hear myself think this literally every time I do it even though it takes half a second at this point

    It is still rather disturbing to me how quickly you an post photos of rat's junk? :confusd:

    OP, once you get use to seeing them and a little confidence it will come easier. :gj:

    Some of the best ways to learn anything is with a visual. Just showing the op what to look for since he was unsure.
