Zoologist Nola Lee Kelsey has worked with animals all her life, from ranches to rescues, zoological parks to behavioral research projects, this life immersed in nature ultimately led her to writing educational books about animals. After suffering a retirement fail, Kelsey put her animal care skills to work as a live-in home pet sitter. That's when she noticed the need for a good portable record keeping system for pet sitters. Naturally this book followed.
