Cat lovers will want to check out this collection of resources created and compiled by the Biodiversity Heritage Library (BHL) dedicated to feline history. At the heart of this collection is a new digital exhibit entitled, "Wild Mouser to Household Pet: A History of Cats in Science and Society, 1858-1922." In this exhibit, visitors can explore via an interactive timeline that charts how cats emerged as a popular pet in the early twentieth century. This exhibit illustrates through a number of fascinating primary documents that popular perceptions of cats in the late-nineteenth and early-twentieth-century were informed by depictions of cats in art and literature and discussions of cats in scientific publications. In addition to this exhibit, the BHL collection also includes a few articles about cats from the Library of Congress and BHL, along with a helpful booklist for those interested in further research.
