Query: Picture shows different product.

I ordered the cubes thinking the Alfalfa cubes would be shipped to me. I received the Timothy Cubes, which are different than the picture. The Timothy Cubes were harder than a brick. I would never give my 6 year old guinea pig old something old and stale. I threw them in the trash, and Amazon refunded my purchase.
