Answer
Every rat is  built different. Some are more petite than others.  However, you may be using the wrong diet on your rats. You may not know this but rats live much longer than the predicted 2 years if they are fed a low protein diet. High protein diets cause their kidneys to fail as they get older which causes early death for them.  A bad diet is just not good for any living thing and the foods sold at pet stores to the public are not good diets for rats.  Please go to my website, sandyscrittercity.com and check out the page on diets for rats. Its not expensive to follow and your rats will be much healthier in the long run.

Also, your rat may have a problem you do not know about such as worms. If once she is on a good diet she continues to lose weight, she should see a vet that knows about rat care.
