hi everyone, I have two male rats who are about 7 months old and recently decided that I wanted to get them two new baby boys as their cage is easily large enough. Unfortunately I just came home from a very long drive the pick them up and I’m worried that one of the new babies is actually a female! They’re happily running around and not nervous at all so I don’t think they could be ‘sucking’ their balls up out of fear but I can’t see any, aswell as this however I can’t see any nipples either! It costs a fortune where I live the get rats desexed (about $250 each!!) but I would happily get the single girl desexed if necessary. If I did this could the fixed girl live peacefully with intact male rats?? Thankyou for your help!!
