Healthy mouse

This morning while eating breakfast we heard a rustling sound. I tried to find out where it was coming from but the sound stopped. Later when I went into the dining room to get a cough drop I opened the cabinet where I'd left the package and found little scraps of paper wrappings and a couple of chewed drops. It was a fresh package of about 15 or so only a couple of days ago. We should have no mice with coughs or sore throats for a day or so.
