I was on the train coming home from work the other day and I heard these teenage boys laughing and the sound of a cat in distress. I said to them I dont like the sound of that, I hope that cat is ok.

They were watching some sickening clip of a cat - I cant even bear to say what was going on - I didnt see it - I turned away and closed my ears so I could not hear the sound. My work colleague had words with them about how it is not funny to watch an animal in distress (and he doesnt even like cats).

I felt and still do feel physically sick to know there are clips going around of such depravity - but how do you catch the culprits that are the source of such evilness.
