I know that cat food works, and I was trying to avoid catching my cats, as I know one of them would go in every night to get some good canned cat food. They tell me to put a small can of cat food in the trap and just crack the lid so they have to go in to get it. They did get the marshmallows out of the cage some how and never went in. I have to take my cat food away from my cats every night so that the raccoon don't come and eat it. I did slow one down pretty much with my 22 though!
