I read in an archived thread recently that it is incorrect to use an apostrophe with the third-person neuter pronoun (ie "it") to imply possesion.
In other words, you shouldn't say - of a cat for example:
"It's fur is shiny and black"
Is this correct? If so, how then does one imply possesion for an object/animal/person when it has no gender or the gender is not known?
Does one have to use the more cumbersome: "The cat's fur is shiny and black" every time - even if the words "The cat" were used in the previous - or even the same - sentence?
