Hello!

In my story, a group of first-years sneak out of the castle at night spying on their young professor. She catches them but shows them her secret, which is that she is harboring a crup in the Forest, a crup who still has his forked tail.
I know that the law dictates that crup owners must have a license and must Sever the crup's tail at an early age. My story is that the professor's brother neglected to get the crup's tail severed (and probably didn't have a crup license). When he was "incapacitated" (sent to jail on an unrelated charge), he left the professor in charge of the crup. She, too, has no license, and is left with the problem of an illegal crup. Any ideas as to what the laws/penalties are concerning illegal crup ownership? Just looking for a bit of brainstorming here, really, and any thoughts on the topic are welcome.
Thank you!
