Finnian has stepped up his counter surfing lately, since scoring some bread and a bag of bagels. So, we laid a trap for him. Put several empty soda cans and a couple with coins in them connected with strings on the back of the counter. Then made a small sandwich with peanut butter... laid the strings in the middle and set the sandwich at the edge of the counter. It took two days for him to snag the bait, but the sound was frightful and he's not surfed since. I have a sneaky suspicion that we'll need to do this again, maybe in a month or two.
