I actually saw this add and thought, "These little fluffy bunnies do not look wild, WTF is mom doing letting loose a pet bunny in the forest?".
I would like an Aussie to respond to this thread. If I recall, rabbits are on a 30 year cycle down under. Their population builds for 30 years untill there are too many of them for the eco-system to support, they eat everything in sight and then starve to death by the millions. The very few that survive begin the proccess anew. Austrailia has been really screwed up by the importation of rabbits.
I lived in Hawaii for a year. The big fear there was snakes. If snakes were to make it to Hawaii, and get loose, they would thrive on the birds that have never lived with preditors. The Hawaian bird population would get wiped out in a few years they predicted.
The bottom line is; "It's not nice to fool Mother Nature!"
