No one would ever say 'Our cats are tall' - only 'Our cats are big' or 'large'.
Is 'Unsere' here used due to cats being feminine or plural? Or Unser would work as well?
So, is it okay to call an animal big using "gross" (apologies for the spelling, I can't type the correct form) but not a person? Does "gross" in terms of describing a person only tall? I read on another post here on Duo that it means tall for people and is never used as a translation for big.
