Okay so they figured it out

Christopher finally noticed that the dog and the cat are gone. He said tonight after seeing a pet store commercial that we needed to go get dog food. AND I said, honey haven't you noticed that Suki and Molly aren't here any more. He looked around and says "well where did they go". I sat him down and explained that Molly and Suki decided to get married and they moved in with their new families a couple of weeks ago. He say "oh well can we get more cats". He is just too funny.
