This book is about cybernetic intelligence that consist of a theory of cat (eco)system, cybernetic control of cat, reasoning of cat system and knowledge representation of cat system. In CAT AI, i look at the predicate scheme, syntax of predicates and sentences, semantics of predicate scheme, domain of discourse, tests and predicates of cat intelligence itself. In the appendix chapter A is given to explore the simulation modeling of cat in a systemic simulation manner by logical reasoning. There, a logical reason-ing of cause-effect cases are provided as if-then cases and if-else cases. A simulation behavior technique is employed in doing so. This is the requirement analysis of a systemic simulation. Furthermore, are the simulation relationships used in the simulatiom modeling exploit. The complete source code in python language is provided along with others like SQL language for AI testing of the concepts or ideas in Appendix B of this book.
