People who walk around very busy areas with non-dog pets (birds / rabbits / lizards etc)

Are they ever normal? Is it an attention thing? Not only in Taiwan, but also overseas. This seems to be an easy way to identify odd folks. Not saying these people are like dangerous or anything, just...a bit off

From most normal to weirdest, my order would go:

Cats >rodentslizards>birds>>>>arachnids

(And I do acknowledge that any pets should be able to get out and get some fresh air. Props to these owners for that. But just one look tells me that this isn't usually their primary motivation) Thoughts?
