Although cocoa pebbles say gluten free and do not contain any obvious animal products, I read that they may or may not contain vitamin D3 that is synthesized from lanolin, which is derived from sheep wool. There is vegan vitamin D3 which comes from lichen...so I am unsure as to where it comes from in the cocoa pebbles. To play it safe, you can buy a labeled vegan chocolate rice cereal. There are quite a few brands that make it, however many are made in facilities with nuts...so please read your labels if you have nut allergies.
