Tigers not agressive?!
The ones up your way must be smoking something.
I used to keep snakes when I was younger, venemous and not. Tigers are the most agressive snakes I've ever encountered. Where Cobras, Puff Adders, Rattlers etc. will give you fair warning and mostly run away, Tigers seem to take offence if you're within 20 metres and activley go on the offensive! Brrrr.
One chased me across the garden last year and my next door neighbour almost died from a bite she got while
standing still.
Give me your nice placid Browns and Red-Bellied Blacks any Day.
