My Gwennevere introduced me to Gluten Lovers Anonymous, the club for cats who cannot resist anything that involves flour, no matter how hard they try. She too eats through plastic to get at any kind of bread, loves any muffins or breads on the counters, even samples goldfish crackers if they fall on the floor. My first experience with this was when she was a kitten. I had made blueberry muffins and left them to cool in the pans. I had trouble removing them but not her! She helped herself, threw one on the floor and had a nice bite. Bagels, banana bread, even a crepe once. She's the only cat I've ever had that gets excited if you put a piece of a roll in her bowl. And never eats the whole thing, just nibbles enough to ruin it. SOmetimes she will gnaw on both ends of a wrapped bag of bread.
