If i recall that particular cat had some kind of hormonal problem that caused aggression, which could be treated with medication and behavioral training. However from reading the article the cat was kicked by one of the family’s kids so he would likely do best in a household with no kids.
Edit: Bingo, i remembered correctly
Lux was diagnosed as suffering from feline hyperesthesia syndrome, a complex condition that may sometimes cause a cat to lash out with outbursts of violent behavior.
