Are table scraps OK for pet rats?

Rats LOVE most human food. Avoid too much fat, protein or fiber. Chicken bones are very tasty and safe. Unlike dogs, rats gnaw bones to bits. A diet of table scraps would likely be too high in fat to consider. As a treat it is okay. Avoid chocolate as it is very high in fat, sugar and caffeine, which is not good for small animals. Rats have a high heart rate and caffeine raises the heart rate. Chocolate is poisonous to dogs.
Fruit and fresh or steamed vegies are much relished by rats, but only give as treats, not as a diet. Avoid iceburg lettuce as it is mostly water and can cause diarrhea.
