Goats are attention whores too

My sister tried raising goats as pets in her back yard. She actually has a rather large backyard around 3,000 sq metres so we didn't think it would be difficult as many people say goats are hardy animals. They got into soo much mischief that my sister finally gave them away after 6 months. They escape from their pens on a regular basis. They eat almost anything and break anything they can.
