From Suming's perspective, adopting any animal was the same; the notion of 'all creatures being equal' precluded the idea of one being nobler than another.
But in reality, the significance of Jacky adopting an animal was entirely different. The choice of animal often reflected the celebrity's personal interests, hobbies, and values in the eyes of the public. For instance, if Jacky were to adopt a crocodile or a piranha, it wouldn't be unacceptable, but such a choice might lead people to believe that Jacky had an inherent liking for brutality, which could be worse than not adopting at all.
Therefore, the animal to be adopted should be comparatively adorable and people-friendly.
