Benny loved cheese on toast, it was the one thing I would bribe him back with when he decided to live next door (only cat to abondon us, very rude since we got him from the RSPCA)
Fizzy had a thing for twisties.
Old Puss loved sponge cake. I baked a pair for my brothers birthday and had left them to cool before sandwiching. Came in a found a hole eaten in one, 15cm wide by 1cm deep. Cheeky old thing.
