To my family and friends who put up with my absence throughout this
process and support me in all my endeavors, no matter how crazy they may sound.
Thank you Keith and Cooper.
To my present animals that sat keeping me company and kept my feet warm as
I worked on this project.
To my past animals who inspired my need for greater knowledge and became a
part of this project as case studies or images.
To everyone who came to my aid as I begged for images and came
through with a great selection.
To my students who inspire me and believe in what I am doing for them.
And to my friend Michelle who spent countless hours helping
me edit as she “did not want to have me look bad.” I could not have done it
as well without your help.
