I think we would need to make a distinction between holding a wild animal in captivity temporarily and owning one as a pet or as an exhibition at the zoo. When people help wild animals that is of course good for them, and it helps preserve wild life. Having them as pets on the other hand is a different matter, and I would be very skeptical even if the animal seems happy because ultimately it would not know or have awareness of what is really going on. That said, it's a complicated issue, so it's not like I'm saying no one should own pets.
