O que exatamente Aberforth Dumbledore fez com as cabras?

Do Caldeirão Furado :

J. K. Rowling was asked in 2007 what exactly Aberforth did to the goat to be prosecuted. Below is a transcript of the interview:
Q: In the Goblet of Fire Dumbledore said his brother was prosecuted for practicing inappropriate charms [JKR buries her head, to laughter] on a goat; what were the inappropriate charms he was practicing on that goat?
JKR: How old are you?
Eight.
JKR: I think that he was trying to make a goat that was easy to keep clean [laughter], curly horns. That's a joke that works on a couple of levels. I really like Aberforth and his goats. But you know Aberforth having this strange fondness for goats if you've read book seven, came in really useful to Harry, later on, because a goat, a stag, you know. If you're a stupid Death Eater, what's the difference. So, that is my answer to YOU.

Além disso ... Nós não sabemos.

Ele tinha um "fetiche por cabras", mas "não estava realmente apaixonado por elas".

De uma carta que Rowling escreveu para um fã em 2008, que recentemente foi parcialmente postada on-line :

3. Why is one brother in love with goats and the other brother gay?
This question made me roar with laughter. Aberforth's goat fetish is [?a ru]nning joke that kept me amused. I don't think he's really in love with [?them, but] it's a good pretext for humor. And I always saw Albus as gay without really knowing why. I knew he had this great freindship with [?Grindelw]ald, and I suspected he overlooked Grindelwald's very obvious faults [??because h]e felt something warmer than ordinary friendship towards him.
4. Don't you feel badly for Kendra?
[?I thin]k you are asking this independently of question 3, aren't you? I [?hope you'r]e not asking whether I feel sorry for Kendra that she had one [??????] son, and one gay son?
