Message From Buttons?

Above, Siren.

Until a week ago Tuesday, we had two cats: Buttons and Siren. Buttons passed away at age 16 on November 8.

This week, Jessica and I noticed something different about Siren. She started to occupy the top of our sofa's backrest where Buttons used to sit. Then she started sniffing our hair exactly the same way Buttons used to (she'd push in the back of our heads with her nose). Siren never did this before. Jessica said Siren started doing this three days ago, exactly seven days after Buttons died.

It is freaky that this started suddenly. I told my daughter Amber about this and she found this to be freaky as well.

Maybe Buttons was sending a message?
