re: I'd rather you didn't move tigers to northern Canada
We already have a problem with nuisance bears, wolves, and mountain lions. These big animals tend to be attracted to human settled areas in search of scraps, garbage, pets, and other tasty treats. Just like a bear and a wolf have their natural instincts (they're really smart) I expect a wild cat to be just as smart. In fact seeing a wild cat is very rare, that's how smart they are. I definitely think letting loose a few hundred tigers to roam free is a bad idea.
