The term 'sty occupants' refers to three different types of animals: slobs, HOGS, and SOWS. Slobs are five-letter animals that are typically found in a pigsty, while HOGS and SOWS are four-letter animals that are also commonly found in a pigsty. Slobs are usually the largest of the three animals, while HOGS and SOWS are smaller. HOGS are typically male pigs, while SOWS are female pigs. All three animals are kept in a pigsty for breeding purposes and to provide food for humans.
