Can you feed rats chocolate?

Chocolate is one of, if not the greatest, inventions of man-kind and is loved by billions of people globally. However, some pets including dogs can not eat chocolate due to the presence of theobromine components which is toxic. Luckily, unlike like dogs, chocolate is technically safe for your pet rats consumption. Although this doesn’t mean you should go out and start feeding your pet rat bars upon bars of chocolate.

Chocolate is comprised of many trace elements, one of which is Caffeine. Excess amounts of caffeine can act as as stimulate to your rats, causing an increased heart rate which can be dangerous for rats with underlying heart conditions. A study on pregnant rats by the University of Wisconsin School of Medicine showed that daily consumption of 4mg or more caffeine had multiple effects including “decrease in the birth weight of offspring and developmental malformations” GILBERT, E. F., & PISTEY, W. R. (1973). Dark chocolate contains 4.3mg of caffeine per 10 grams.

Milk chocolate

Milk chocolate is the most common chocolate consumed among humans. However with an almost 30% content and 50% sugar content is not the healthiest treat for you rat if you choose to give them chocolate. Try to avoid giving rats milk chocolate in the form of M&M’s due to the additional sugar.

White chocolate

White chocolate is fattier and contains more sugar than milk chocolate containing 32% and 59% respectively. Although technically rats can eat white chocolate, due to the high fat and sugar content it isn’t recommended. If you wish to feed your rat chocolate you give them dark chocolate as an alternative.

Dark chocolate

Dark chocolate is the best chocolate option when it comes to rat treats. Containing less than half the amount of sugar than white chocolate (24%) and only 43% fat content. We recommend feeding pet rats dark chocolate over other chocolates as it is the least fatty and contains less sugars. Although dark chocolate is “healthier” than other chocolates for rats it still needs to be feed in moderation as a treat not a main component of their diet.
