Usage . While it is possible to use ITS as a predicate adjective ( The cat is angry because the bowl you're eating out of is its! ) or as a pronoun meaning "that or those belonging to it" ( Your notebook pages are torn. Borrow my notebook - its aren't ), such use is rare and in most circumstances strained. See also me .
