The difference is that Charlotte is a foreigner, and that where she comes from, Ravens are popular familiars. Ferrets on the other hand aren't really seen or mentioned at all from what I know (outside of a single mentioning of charmed ferrets in one of the books.)I don't remember this, can you remember where you're getting this information? That was quite a long time ago, and regulations may have very well changed since then.
His character seems to be foreign too? Or even if he isn't- I'm not sure why that makes a difference. Like I mentioned before; this is our roleplay not a re-inventing of the books or movies. It's up to GM ultimately; but I doubt it will be any problem to them.
Also, Yog is referring to Harry's son Albus- he had a ferret.
