They are very sweet and this is a great deal! I will also include their 3 story cage which is metal painted black, two food bowls, one water bottle, a small green igloo, and a spinning wheel. A small travel cage will also be included. They are young, I bought them at Petco when they were medium sized two months ago. They are very curious and love to explore secured open spaces, such as a bed because they will not jump off with supervision. The large cage has some rusting in the bottom corner due to being a few years old and having previous rat residents.
