Cats are like crocodiles, they are top of the food chain. You don't domestic a crocodile and then release it and worry about how its gonna survive. By your rational those poor girls that that German bloke had locked up in his basement for twenty years don't stand a chance of rehabilitation. Bats are way down the food chain, they are mice with wings. Move to Darwin Australia, get your Mango tree infested with protected Flying foxes, wake up and smell the guano each morning, knowing full well there is nothing you can do about it but move and we'll see how you feel about bats!!!...They are cute little critters though aren't they!
