These are very social animals. They normally live in large groups with complex social interactions. It's cruel to keep one alone. They are also very intelligent and need mental stimulation. This poor animal, all alone in a cage too small for it to fly, with nothing to occupy its mind, has gone insane, and is biting the cage wires in its desperation. No, it's not cute. It's about as cute as keeping a child in an empty closet.
