Actually what animal abusers really need are not punishments, or imprisonment but therapy. There's defintely a reason for their cruel behaviour and it's a condition that society should look into.
Nobody would wake up one morning and say, 'I think I'll kill a cat today!'
Hurling insults at those people, hoping they die a thousand and one deaths in a thousand and one ways won't do anything except feed the ego. To be honest, we're no different from them. Would u save someone who's being surrounded and attacked by a group of men? I tell u most of us would just pretend and walk away.
I'm not saying I won't get angry if I see someone stepping on a cat, of course I will.
