It was one of those days ... First , we go by one of those big box pet stores to get some cat food . Yeah , so sorry kitties for the half rations last night . I just could n't face going out at 7:30 pm to get you more food .

Answer: There was n't enough cat food .The cat food ran out days ago .None of the above choices .The pet store was closed .
