I once bought a spicy chicken sandwich, and Freya started harassing me for it just how you would expect a cat to do.
So I tore off a small piece of the chicken and let her look at it and then she was absolutely mystified. It was breaded and spiced, so not edible for cats, but it smelt like chicken? How could this be???? What is this???????????
She stared at it, pawing at it and trying to eat it for like, 10 or 15 minutes.
