I know someone who had a pet Tarantula, he left in about the mantlepiece one day and left the fire roaring.
He thought he damn spider would just move if it got too hot but beleive it or not, he came home from shopping to find his spider curled up dead in the same postion as he left it!!

On another note, my dad converted his tropical fish tank into an african tree frog tank.
We fed them crickets. One day the frogs managed to escape and to this day my old man does not know how.
My sister went to school and one jumped out during her exams. Quite funny indeed!

And there was still one missing... My dad went through to fed the ones that havent escaped in the morning, He walked through in his slippers and dressing gown and heard a squish as he put his foot down.

Lifted up the slipper to find the frog sticking between the floor and his slipper covered in goo.

These creatures are meant to live in the wild and I think it's really selfish to try to domesticate them just because it's 'cool' or unique to have such pets. It's a poor deal for both the owner and the pet. I hope is guilty about having caused a python to be put down because she and other irresponsible animal breeders try to defy the law of nature.
