Kayakcrazy is crazy, You don't feed a Mexican mouse peanut butter. Pending the color of the mouse, if it was a dark grey it will like the mild salsa and if it is light grey the hotter the better salsa. Also the light grey do not have droppings, it is in a hot streak rather than pellets. I am hoping it was a solo mouse and male also because if it was a female, she would be upset being called Speedy Gonzales. If it was a Canadian mouse you can look in your refrigerator to see if there is a foam container like you get night crawlers in. It will say Canadian Mice. If it an American mouse you should see bottles of cheep tequila under the bed. Hope this helps.
