Your pets’ main diet should consist of rat blocks, a high-quality pellet chow formulated for rodents. Look for a brand that lists soy meal as the main ingredient. This food should be available at all times.

Offering small amounts of fresh fruits and vegetables to your rats every day. Peas, broccoli, carrots, apples and bananas are good foods to start with, but it’s fun to try new things and find out your pets favorites. Rats love people food, and you can give yours the occasional table scrap, such as cooked pasta, small pieces of egg or chicken, or a bit of pizza crust. Treats need to be limited to prevent obesity.
Do not give your rats chocolate, corn, candy, caffeinated and carbonated beverages, onions, sticky foods such as taffy and peanut butter, and junk food.

Fresh, clean water should be available at all times. A water bottle with a drinking tube that attaches to the side of the cage is the best way to go. However a small bowl of water on a shelf will also do the same job.
