What is the difference between who's and whose?
Who's is a contraction of "who is" ('Who's there?') or "who has" ('Who's got the time?'). Whose shows possession ("Whose shoes are these?"). In this case, as for it’s and its, the apostrophe stands for missing letters—not possession. Remember that possessive adjectives like my, your, his, her, and its do not have 's, and neither does whose.

As a general rule the more impersonal the thing is, the less likely it is to take 'whose'. For a person, always.
What is the difference between whose and animate?
