1909 - Eunice E. Gibbs Allyn publishes The Cats’ Convention, featuring her drawings of cats

From Encyclopedia Dubuque:

“Allyn’s The Cats’ Convention was published by Cochrane Publishing Co., New York (1909) and was reviewed by Watson’s Jeffersonian Magazine the following year. The work is illustrated with drawings of many cats of various styles of attractive beauty and picturesque ugliness, all created by Allyn.”

The dedication in the beginning of the book reads: “To all GOOD CATS and LOVERS of CATS this book is affectionately dedicated by THE AUTHOR.”

The last time I checked, there are reprints still available here.
