Is it grammatically correct to use "who" for inanimate objects?

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?
