Instead of the dry cat food use canned as it has a stronger aroma. When using marshmallows I add a few drops of liquid fish oil for the same reason. I added fish oil to some dry dog food in the live traps to deal with a family of skunks that recently moved under the shed. Canned cat food, marshmallow, and fish oil is a very strong attractant. It also attracts every other creature around so I limit my use to when I have a known threat.
