100+ kg aren't goats, those are wildebeasts!!!
That is funny though, because way back in my childhood my father won a goat in a bingo game (yeah, they did that back in the day). We called it Rusty (all us kids had "R" names and so did our pets - except DC the cat, named after the Siamese in the movie That Darn Cat), and it was a very Randy goat. Whenever my sister or mom left the house, it would go after them like its life depended upon mating RIGHT NOW! I remember them having to run to the car just to get into it before Rusty came around from the backyard. I don't know exactly what happened to that guy, but I think my dad finally gave it to someone with other goats (and other animals, I believe) for him to be with.
