Where Did Everyone Go?

I am so sad, I have been just lying on my blanket and hiding my head in my paw all day. What happeneed was that I went to go look out of my window to see my peeping friends, and they are GONE! I don't know where they went. They were there one day, and they disappeared. They just flew the coop without saying good bye to me. What is a cool cat to do? I miss my chirpy friends already.
