Give it to them inside a water bottle. Hang the bottle on the side of the cage with a metal hook that you should be able to purchase with the water bottle.
they should eat the normal guinea pig food and drink from the water bottle.
No. The 20 ounce bottle is just a tiny bit short of 0.6 liters.
If the color of the bottle is green it is okay. If the water is green you have a problem.
