do you know the difference between curiosity
Your post was so long , I didn't read it :/
I hope you are a (or an aspiring ) biologist ...because you are too obsessed with this topic.
I am curious and I googled for about 5 minutes, watched a clip from David Attenborough (great man) where he describes the Tiger as the largest cat....in fact calls it a super-cat ...
I am more concerned about tigers/lions being hunted by man and losing their habitats and planing my weekend =)
Relax, have a cup of tea. Go outside !
Tiger wins though
