CULPRIT USUALLY AGGRESSIVE: DOCTOR
If the cats were killed by someone, the question arises as to who could have committed such an act.
Dr Adrian Wang, a consultant psychiatrist at Gleneagles Medical Centre, said: "People who commit these acts suffer from anti-social personality disorder.
"They have a high capacity for cruelty with no sense of remorse."
Dr Wang said while their actions may never escalate to hurting people in the future, these people tend to be aggressive and do not respect other people's boundaries.
He also said that these people tend to be bullies.
