Obesity

                           -------



The tendency to become overweight (often grossly overweight) is

more often a problem of pet rats than mice.  Overindulgent pet

owners and diets rich in seeds and nuts are most often

responsible for this condition.  Owners of pet rats must resist

the temptation to feed junk food, such as french fries,

doughnuts, cookies and candy.  Commercial diets specifically

designed for rats are always preferred and can be supplemented

with whole-wheat bread, dry cereal, pasta, fruits,

vegetables and non-fat yogurt.
