I believe if you get a wild caught animal and give them proper space and care, and that the animal isn't overly stressed being in an enclosure that it's fine. I've raised a wild caught toad, and she's become so dependent of me that she would never make it in the wild. And I see it that if you are able to catch the animal, anyone could of caught it and that person could take improper care of the animal, hurt it, kill it, etc. Better for it to be safe in a good home.
