Day 2: No Raccoon, Yet

The second night of having a baited trap came and went with no raccoon to be found.  Last night was pretty rainy, so perhaps he stayed at home and didn't venture out to take a HUGE dump in my garden.  Alas, per the recommendation of the trapper, I left his latest pile in tact and when I went out to inspect, there wasn't a companion turd from last night.  So, at least that's a positive, right?

In addition to moving the trap and in a further attempt to make the trap more appealing, I cut up an apple into wedges and added that to the sausage wrapped in tin foil, but it (apparently) wasn't enough. 

Per the recommendation of Nat's Aunt, I'm going to up the ante and go with a can of cat food or tuna fish and really try to lure him in tonight.  Those items were both mentioned by the trapper, too, so I'm thinking they may work.  But, do you guys know?  Do I just open the can and take the lid off?  Then put the entire can in the back of the trap?  Or, should I dump the contents out onto something like a plastic plate?
