Think our two would eat just about anything... I have given raw carrots, cabbage, broccoli, spinach, sweet potato, etc. Fruits; pears, apples, pineapple, bananas, peaches... and so it goes. I do use the food processor & add to their meals, but also use as treats. Think we all know, no onion ever. They have also tried a CD, underwear, magazines, and my favorite wool clogs. Didn't mention just nibbles on the coffee table... Jeanne
