Cabbage.

Feeding cabbage to hamsters should be avoided. Although cabbage possesses valuable properties for humans of having sulphur, chlorine, and iodine content. The combination of sulphur and chlorine causes a cleaning of the mucus membranes of the stomach and the intestinal tract, this acts as a laxative. Cabbage also acts as a diuretic, a substance that causes increased urination, and tends to increase the secretion and flow of urine. Broccoli can also have a similar effect. A small quantity of cabbage may be fed to a hamster if he is constipated. Feed it raw as the longer cabbage is cooked the less digestible it becomes.
