Someone Ate My Trash Cookies!

I bought one of those packs of Archway cookies. After I opened it, I placed them in a plastic baggie to ensure freshness. After eating 4 and then feeling ill I decided to throw them away.

ATHANATA AND THE MYSTERY OF THE TRASH COOKIES

Take in mind, my detective friends, the following items.

ITEM A: I took out the trash last night at 11pm. The trash was picked up around 7 AM.

ITEM B: On top of the cookies (in the trash), was a plastic bag full of cat litter.

I awoke this morning to find the trash removed, but lying in my driveway were:

1. An EMPTY plastic baggie FORMERLY containing Archway Cookies. The cookies had been carefully removed from the original archway packaging (still retained within the plastic baggie. There was no sign of struggle/ripping of cookie container.

2. An avocado pit, lying around one foot away

3. Emptied trash bin.

This leads me to three possible conclusions:

I. The Garbagemen ate my trash cookies. Avocado pit thrown in spite.
Rank: Low - The bag was tied. Why would they open it up, remove the cat litter, then eat my cookies and toss them on my driveway

II. A Raccoon ate my trash cookies. Avocado pit thrown in joy.
Rank: Low - the cookies were too carefully removed from the pack - there was no other trash on the ground.

III. A transient/crazy person/gutter punk/scavenger ate my trash cookies. Avocado pit thrown in victory.
Rank: Middle, but still unlikely. I live in a lower middle class enclave in a fairly rural area. Most people here are in law enforcement and 99% of neighborhood is families with children. The person would have to be pretty hungry to brave the cat litter.
