I am not making fun of anyone here.You would be surprised at how many people do not have a clue as to what those little things are under his tail .I was at a freinds pet store one time and a lady asked him how old those babies were.He responded what babies are you asking about mam? Well long story short,what she thought was some babies were his you know whats! She was so embaressed.Another reason they might not have caught it is male rats will pull them up sometimes and a quick glance would look like a female.Originally Posted by Shaffer
