Did you probe the animal and did you do so yourself, do you know if it has been probed previously by someone else?

Did you probe both sides?

Can you pop "him/her"?

While I do not want to give you false hope, it is possible that you have purchased a mis-sexed animal (mistake happens) it is also possible that a female probe male (hence my questions)

Should a female be injured and probing accident do happen "she could now" probe as a male which is why I would recommend not only probing GENTLY the other side but also popping the animal.

Now if it is indeed a Male there is definitely an issue since it was purchase as a female sadly the seller might not make it right, and if the animal was sold mis-sex you also have to wonder about the genetics now
