The second reason is that the skin of grapes can be a choking hazard.  

It’s easy to thoroughly wash grapes before peeling and cutting the grapes into small slices for your hamster to eat.

Your hamster is likely to be a happy hamster indeed!

Your hamster is likely to like grapes, but due to the high sugar and water content you should only offer grapes once or twice a week at most when given as a singular snack.  

Give 1 to 1, 5 grapes (about 1 teaspoon) to your hamster, unless your hamster is small or is a dwarf hamster. Then limit the amount to ½ to 1 grape (about ½ a teaspoon). 

You can give grapes as part of a hamster salad where you mix vegetables, fruit, seeds and nuts. Limit the grape to no more than ¼ of a grape.  

Don’t offer grape seeds, leaves, stems or the skin. There will be too many pesticides present, also the seeds and skin can become a choking hazard.
