Consider the implications of this warning (the rightmost panel in particular) on an escalator in the Shanghai Urban Planning Museum. In a context where pet ownership is on the rise, and behaviors around what is “proper” (or even what a “pet” is) are still in flux, the surrounding urban infrastructure and its accompanying usage guidelines try to keep up – and perhaps influence the definition a bit themselves.
Think of the places in your own urban context where an escalator (or other public pieces of infrastructure and spaces – public buses, metro/subway stops, police stations, urban planning museums, etc.) could potentially be critiqued as being “pet-unfriendly”. How would a “pet-friendly” version of each of those look (based, of course, upon the context’s definition of a “pet” and where said pets are allowed/encouraged)?
