It puzzles me that my current cat, Watchcat Collette, and previous cat, Watchcat Sylvia, have the common bond of enjoying lettuce. I've eaten a fair amount of salad, but salad dressing is mandatory for a salad to be palatable, I think. I can't imagine just eating lettuce leaves without anything on them, but Collette and Sylvia have wolfed down plain lettuce eagerly.
Then again, in a world where people inexplicably seek out the taste of raw celery or pizzas with pineapple, maybe this is less bizarre than I think.
