I thought Bob had been forgetting to push the kitchen chairs back in under the table but it turns out the culprit is Pyxle. Last night as I was at the stove she pushed and pulled one across the floor toward me and then jumped up on it to reach the counter and stove and check out what was up there to get into. So now at least I know how she managed to get the tomatoes off the counter.
Now I have to figure out how to make it so the chairs can't slide so easily. Dog gone it, I refuse to be dogged by a dog while cooking!
