My elderly cat stole my Hello Kitty soft toy. I didn't mind, so let her have it and now keep it next to her cat bed, which is in our bedroom.
She keeps picking it up and carrying it onto the landing and miaowing loudly until someone comes to see her. I don't know what we're supposed to do once we get to her and the toy 
She's never played fetch and she doesn't do anything with it other than just deposit it in another room.
What is she trying to tell us?
