Mine love hard boiled egg. I chop it up into tiny pieces. At first, they weren't too sure, but now they LOVE it. It's fun to watch!
Has anyone tried WeetBix? Here in Australia, its a common breakfast cereal - kind of like Shredded Wheat. I crumbled up a bit of it and they went wild. I didn't give them much because I haven't read of anyone else doing this and I wasn't sure if it was good for them or not. But they love it.
