This was posted a week ago on the Alice In Chains forum, somehow I missed it then. After Layne died Jerry got Layne’s cat Sadie. Here is the story:
Many of you know the story of Sadie, Layne’s cat. She made an appearance in Jerry’s Crib’s episode, along with his brother, David, who just notified us that Sadie passed away. She was 18, she passed away the night of the Seattle show.
