Pet animals play an important role in many people’s lives. Every single year, it occurred increasing enthusiasm of people to get pet. Recently, according to the American Pet Products Association (APPA), almost 85 million households have a pet. Obviously, trends have pets getting popular recently. Many people have pets to enhance relationships with partners, children or family members. Many elderly people like to have a pet as companionship because of loneliness. Adoption in animal shelter is one of the ways that common people do to get pet animal. The animal shelter provides various types of pets based on the adopter needed. The aim of this study was to know the behavior adopter pattern for pet adoption. This study only focused on cat and dog animals. Apriori association rule mining was used for finding interesting pattern from the animal shelter database. Moreover, this study generated models to predict how long pet animal stayed in shelter using machine learning approach from variables found to be important predictor in adoption. Intake reason, age, color, and primary breed were major determinants of adoption in cats. Intake reason, primary breed, color, secondary breed, and age were major determinants of adoption in dogs. Knowing the length of stay of animal in shelter was important, since in the animal shelter has space limitations. In case that it occurred overpopulation so the other problem would arise as maintenance and social problems. The results of this study could help animal shelter employees to increase level of participant of adopters. Once the behavior of adopter patterns was obtained, it could determine which characteristics of cat or dog have in demand by adopters. Furthermore, in case the length of stay of prediction result was long term, it could help animal shelter employees for making good decision whether to defend the animal in the shelter, or take other actions such as sale or donate the animal for health purpose.
