*Whether these foods are safe or toxic is still under debate. Cabbage, cooked potato and cooked kidney beans (both served cold) may be fine for your hamster in small amounts. However, we've added them to the list to be on the safe side.
**Although celery is not generally considered toxic, it is very high in Sodium. Too much Sodium can increase the retention of water in the body tissues, so it is not generally recommended to feed celery to your hamster.
***Even though many people say it's okay to give a hamster seedless grapes and raisins, this fruit has been known to cause acute and chronic renal failure (kidney failure). It is advised that raisins and grapes should not be fed to any animal until more research has been done.
