This will depend upon the size of your hamster, but generally speaking they should consume around 4 teaspoons (20ml) each day. Dwarf or Syrian hamsters may consume less due to their smaller body size, and this is nothing to worry about. You can keep track of how much your hamster is drinking using the measuring lines on their water bottle. If the bottle doesn’t have any, you could use a waterproof marker or stickers to make your own.\r
