Is it grammatically correct to use "who" for non-persons such as organizations, animals?
Consider a question
Q1: "Who should I feed?" and the answer
A1: "Feed the hungry, your friends and your pets."
Would the answer be grammatically correct if it includes "pets", but the question had a pronoun "who"?
A similar example:
Q2: "Who should I donate money to?"
A2: "Donate the money to the poor and to the universities."
Would the example answer be grammatically correct if it mentions universities which are organizations rather than persons?
Who or what are your basic choices here. Pets can also be considered addressed by who.
