Rat Diet: HomeMade - I make my own mix based off of the Sue Bee Diet and feed that along with "Chicken Soup for the Dog Lovers Soul Light" and "AvoDerm Vegatarian Diet". They also get Harlan Teklad Blocks when available. Here is another homemade mix created by Debbie Ducommun. Dry Dog Kibble -Some high quality dog food brands include - Chicken Soup for the Dog Lovers Soul Light, Canidae, AvoDerm, Innova Senior and Wellness. (recommended percentage for rats is 12-15%. Babies and pregnant and nursing does should receive a higher percentage, while adult males should be given less. Lab Blocks - Harlan Teklad and Mazuri are just two of the better quality lab blocks. Lab Blocks are nutritionally designed to meet all the dietary requirements for rats, However many of the ingredients used aren't very high quality. Fruits, Vegetables, and Grains - Here is a list of some of the fresh foods you can give to your rattie daily -- Amaranth, Apples, Apricots, Avacodo (this is high in good fats and should be used in moderation...especially with 'Big Squishies'), Banana, Barley, Beets, Black Beans Cooked, Blackberries, Blueberries, Bok Choy, Broccoli, Buckwheat, Cantaloupe/Melon, Carrots, Cauliflower, Corn, Cranberries, Edimame(baby soy beans in the pod), Eggplant w/ skin, Flaxseed, Grapes, Green Beans, Kale, Kelp, Kidney Beans (cooked), Kiwi, Lima Beans ( cooked), Mango, Millet, Mushrooms, Nori, Oats or Oatmeal, Papaya, Parsley, Peaches, Peas, Plums/ Prunes, Quinoa, Raisins, Raspberries, Red Grapes, Rye, Spinach, Sprouts, Squash, Strawberries, Sweet Peppers, Turnip Greens, Turnips, Wakame, Watermelon Nuts - Almonds, Walnuts, Peanuts, Hazel Nuts...etc. should be given only occasionally. For a boredom buster give them hard nuts (Walnuts, Pecans, Hazel Nuts) in the shell. Forbidden Foods - There are a few foods that should NEVER be offered to your rat. Debbie Ducommun has created a great Forbidden Foods list .
