The most dangerous of this parasitic skin disease is Endoparasite, because this disease is caused by parasites that enter the cat's body and the symptoms caused are almost the same as Ectopasite. In this case objectify the Expert System:Certainty Factor method of cases raised in the study, namely the expert system of cat skin disease caused by parasites and implemented based on Android and built using the SLDC (Software Development Life Cycle) Waterfall software engineering method. In this system there is a disease diagnosis feature, displaying information about the disease and symptoms of skin diseases in cats. The results of this study are 9 symptoms of 2 diseases that processed using the Certainty Factor method. With an android-based application and can be accessed mobile, this make it easier for cat keepers to find out about skin diseases in their pet cats.} }
