Chocolate
There have been many disagreements between rat owners about whether chocolate is safe for rats. Some people say that chocolate can not be digested by rats. Others say that they often feed it to their ratties without anything going wrong. I personally dont feed rat s chocolate(mostly because it is disliked). I dont think it will do any harm though if you feed your rats it. Also, many people say that small amounts of dark chocolate can improve respirator infections in rats.
Peanut Butter.
Like chocolate, many people are questioning whether peanut butter is rat-safe. I think that choking on peanut butter is a valid case, so i tend to keep rats away from it.
