I’m not sure how to ‘like’ this.The window spider is gone leaving behind lots of webs, 4 empty egg cases, and lots of dessicated insect bodies. Perhaps she went to find a winter hibernation place or perhaps that crazy catbird finally managed to get her.

Spider gone =pro.
4 empty egg cases =con.
Desiccated insect bodies =pro.
Hibernation & catbird dinner =mixed.

In an effort to say something nice, sorry this episode of your entertainment is over.
