(Canon to ★Tom and Jerry★.animals can speak only with themselves,) The day went not as usual.The parents were out on a business trip and left Tom alone.From this,Tom stayed on the house and was acting strangely.He didn't react to Jerry's pestering or other mice,not then at the dog outside,not caring if he went inside or not.Tom just stayed on the windowsill and looked out the window with a sad expression.Jerry thought it was strange and spoke with the dog about it. (You're Tom and a male cat.)
