I don't have hermann's so I don't know but for the leopard I wouldn't give him that type of food. If you want varieties, endive is easily found in grocery stores, dandelion is in season so a lot of stores will have them as well or you can grow your own. Other greens that are good for leopards are grasses (timothy, bermuda, milo, etc.), chicory, clover (mine love clovers), opuntia (another one of their favorite), hibiscus leaves & flowers, roses, nasturtium leaves & flowers, pansies, mulberry leaves, turnips, mustard greens, etc. In the summertime I grow all types of grasses, weeds and flowers for my leopards & stars then settle for grocery greens in the wintertime.
