In this sentence, "Either the cat or the dog" is a compound subject connected by the coordinating conjunction "or."

When you have a compound subject joined by "or," you choose the verb form that agrees with the closer part of the subject.

In this case, "dog" is closer to the verb than "cat," so the singular verb "was" is used, resulting in proper subject-verb agreement.

I asked him, “Where will you stay?”

In direct speech, the pronoun and tense are adjusted: "he would stay" becomes "you will stay."

Since it's a question, the correct form uses "will" before the subject.
