Re: dead smell to feces
Hmm, not that I've smelled a dead rat, but it could be a bacterial imbalance in the digestive tract, a bacterial or viral invader/infection, bowel disease, allergy, intolerance...etc.
How is your diet in general...meaning what kinds of foods or liquids do you consume?
Are you on any supplements?
How are your bowel movements in general...how many times? are they diarrhea, solid, hard..etc?
What you should do, however, is request your doctor give you a collection kit for you to provide stool samples so that they can be tested.
It's all a matter of perspective!
