These chips are a "MUST HAVE" because of the rat. Where I used to live I had a fountain in my backyard and some vegetation around one side of it. I fed the birds and squirrels and they would throw seed on the ground. This attracted a rat once and he lived in the vegetation behind the fountain so I set one of those big rat traps to get it. My son (4 yrs old) and I were on the patio when I heard it snap and I knew I got him. When I retrieved the trap with the rat hanging off of it my son saw it and began to cry like I killed his best friend. I asked him what was the matter and he replied between sobs, "I won't have any more rat friends" (meaning Mickey Mouse, and other cartoon characters). He is 28 now and we have laughed about him not having any 'rat friends' ever since. So the Year of the Rat chip has special meaning!
