I need to change the 'Out of Stock' label on product blocks to read 'Adopted' I know,
innerHTML:"Out Of Stock"
innerText:"OUT OF STOCK"
are called by .thumbnail.nostock  but I can't find which template file adds this text. 
Any help I would be grateful.

Fantastic Geoffrey, many thanks for your help. How useful a tool is this!

I've been through almost every file. What file adds the HTML to the .maintext blocks please? I need to change them to more suitable ones :-)
