I was eating (whole wheat) Golfish Crackers the other day and dropped a couple of them on the floor, so I picked them up and put them on the coaster on the sofa table.
(Did you hear that kids? I dropped something, so I bent down and picked it up!)
Anyway ... Olivia, who never has anything better to do than sit and stare at me (when she's not napping), eyed the crackers, and then ate them. I guess cat's do like fish. And, it might be proof that everyone does indeed like the snack that smiles back!
