Okay, weirdness, my boy Fred who has finally recovered from a crusty lump on his neck that became an open wound and required an operation to finally heal, anyway, rubbing his tummy today I noticed that he only had two nipples left, both on the same side and both looking a bit odd (almost as though they are just little crusts and if I wanted I could pull them off... I don't want to!), the other two have gone/disappeared, the lower one just has a tiny pinprick hole where it once was? Any ideas, he is completely unbothered.... I'm sure the other two were there yesterday!
