Why do the animals in rescue have to be displayed in the store?
Hasn't anyone heard of digital photography? Whether it is stills or movies the animals can be photographed and their descriptions can be written by the people who are caring for them in foster situations.
Posters and catalogues could be regularly updated and prospective petslaves could fill out adoption forms to weed out the unworthy.
Would anyone consider displaying adoptive children in a store front?
