I always had a suspicion that cat lovers are usually people with issues. Not a few of them tend to be petty or have some kind of serious emotional deficiency. ;p

Family Conflict Counsellor axes parents to death for laughing at cat's death
Yes, you read it right. The dude, a trained counsellor dealing with family conflict, killed his parents for laughing at him when his cat died.
Some people treat their pets like their kids. I get concerned when I see young couples taking up a pet and calling it their "baby". It might make a psudo child but really its only a temporary fix for what they really need- a human baby.
