We had a cat years ago who loved vegetables. She would eat peas, green beans, corn, carrots, just about any vegetable. And her favorite of all was iceberg lettuce! She loved it. We even tested her once.....held out a piece of meat and a piece of lettuce. Yep, she took the lettuce! Weirdest cat I ever had.
I also had a dog who liked raw carrots and dewberries.
