Cats este o bibliotecă de programare funcțională și type class pentru Scala, concepută pentru a implementa tipare algebrice și abstracțiuni funcționale. Aceasta oferă un set standardizat de interfețe și un toolkit modular de wrapper-e și containere funcționale pentru a permite polimorfismul ad-hoc și programarea generică între tipuri disparate. Proiectul servește drept standard de abstracție funcțională, oferind o suită de monad transformer pentru a compune contexte imbricate cu efecte și a gestiona multiple efecte secundare computaționale într-un singur pipeline. De asemenea, permite construirea de limbaje specifice domeniului (DSL) încorporate prin reprezentarea logicii programului ca structuri de date care sunt interpretate separat de definițiile lor. Biblioteca acoperă domenii largi de capabilități, inclusiv manipularea algebrică a datelor pentru combinarea și reducerea valorilor, gestionarea stării cu tipizare sigură și gestionarea funcțională a erorilor pentru a formaliza acumularea și recuperarea acestora.
