Rats need not only their own bagged rat food but they also need some fresh foods and cooked foods. This is steamed white rice mixed with 2 tablespoons of canned corned beef hash. The boys loved this for dinner. Don't let the size fool you, this is a very small plate and it's feeding several rats.
Lucky knows when I'm cooking dinner that he'll be getting a little something as well and he sits at the front of the cage giving me this look. *food?*
As well as steamed white rice, I give my rats fresh fruits and vegetables, cooked noodle, boiled eggs, and little bits of other things that I make for dinner.
In order for a rat to have a balanced diet they need the additional fresh fruits, vegetables and other foods. Plus, wouldn't you get bored eating the same thing day after day? They do too.
