Q. How long does it take for cat food to go bad?
JESSICA L DESROSIERS
A. Cat food should be used ahead of the "best before" date that is printed on most labels. Store food off the floor or in a container in a cool, dry location to reduce the chances that mice, insects, or other vermin will gain access to it.
Dry food can be left out in bowls as long as it is not exposed to moisture or hot temperatures. Wash and refill food and water bowls at least once a week. Canned food should be discarded after it has been at room temperature for four hours and the bowl is cleaned prior to being refilled. Opened cans can be stored in the refrigerator for up to seven days.
