Is there something missing?

Confession: I found myself stolling through the aisles of PetSmart this evening and I don't own a pet...not even a fish.
This is not the first time it's happened. I go and look at the doggie beds, the doggie clothes, the doggie toys, read through the doggie magazines, watch some little doggie get his hair cut, and have a peak at the little kittens in their cages.
Am I warped or is there something missing in my life? I think there's a clue in the fact that I call everything as PetSmart "doggie" something...hmm
