Canned pumpkin (not pie filling) isbest. Other then that herbs (like mint, parsley, cilantro,dill, etc.) are very good for GIS too. An article we havesays the stronger the aroma of a bunny safe vegetable/herb, the betterit is for GIS. Break the stems right before giving it to thebun to tempt him/her to eat it. If they aren't eating, then asyringe of canned pumpkin or a pellet slurry (four and a halftablespoons pellets to a half cup water, let soak ten mintues, then putin blender for another five minutes. It should go through alarge feeding syringe after that) fed into the side of their mouth inthe standard feeding aide way will be necessary.
