Can Rats Eat Raisins? What You Need to Know

Can Rats Eat Raisins

Raisins are tasty and relatively healthy snacks for us humans, and we know our pet rats enjoy sweet fruits in their diet. As pet owners, we understand that animals can’t always enjoy the foods we do, for a variety of reasons. But can our pet rats eat raisins? The short answer is, yes! 

There are some things to consider before feeding your rat raisins, though. Raisins have a very thick, gooey texture and it may be difficult for your rat to chew. We want to avoid the choking hazard they present so it’s best to cut them up into very tiny pieces to make them easy to eat.

Another thing to keep in mind when feeding your rat raisins is that they are pretty high in sugar, and you don’t want your rat consuming heavy amounts of sugar, even if it’s natural. They have sensitive stomachs, and an overload of sweetness isn’t good for their health. So as a rule, it’s best to feed them raisins sparingly, no more than once per week. Otherwise, raisins are rich in magnesium and potassium and make for a great source of antioxidants.


What Does a Rat’s Diet Consist Of?

It’s no secret that in the wild rats will eat just about anything they come across. They have shorter lifespans in the wild due to this reason. They tend to eat very unhealthily as they rummage through human garbage and eat as much as they can. They’ll also unknowingly eat poisons set out by humans simply because it tastes good.

Pet rats generally live longer thanks to their human companions that keep their best interests at heart. Most rat owners do their research and understand what kind of diet to feed their rats to ensure their overall health and well-being. What does that diet look like?

Rats need 80% to 90% of their diet to consist of high-quality pellet mix formulated for rats. Another 10% to 20% of their diet should be fresh fruits and vegetables. Rats are omnivores, so they can be given occasional treats such as meat, certain nuts, and seeds. Like raisins, these foods should be fed sparingly due to being high in calories and fat.

What Foods Shouldn’t I Feed My Rat?

It’s important to know what kind of foods you need to avoid when feeding your pet rat. We’ve put together a list of foods that are either best avoided entirely or should be fed very sparingly.

  • Artichoke (avoid, rats cannot digest)
  • Alfalfa (avoid, rats cannot digest)
  • Beans (raw beans will deplete vitamin A and destroy digestive enzymes in rats)
  • Beets (high in oxalic acid, can cause kidney stones, calcium deficiency, and other health issues)
  • Bread (feed sparingly and in small amounts)
  • Brussel sprouts (avoid, causes vitamin B1 deficiency in rats)
  • Caffeine (avoid)
  • Candy (avoid, high in sugar)
  • Chocolate (avoid, contains high sugar and caffeine)
  • Red cabbage (avoid, causes vitamin B1 deficiency in rats)
  • Iceberg lettuce (high in water content, no nutritional value)
  • Leeks (avoid, choking hazard that can cause upset stomach)
  • Onions (avoid, can cause anemia, and upset stomach)
  • Peanuts (avoid, can destroy digestive enzymes and deplete vitamin A)
  • Spinach (feed sparingly, if at all, high in oxalic acid, can cause kidney stones, calcium deficiency, and other health issues)
  • Rhubarb (high in oxalic acid, can cause kidney stones, calcium deficiency, and other health issues)
  • Swiss chard (high in oxalic acid, can cause kidney stones, calcium deficiency, and other health issues)



Rats can most definitely eat raisins but it’s best to offer them sparingly due to the high sugar content in this tasty treat. You need to cut the raisin into very small pieces due to the thick texture. This will help prevent the raisin from being a choking hazard to your rat. Overall, they are healthy and rich in vitamins and nutrients.

Pet rats rely on their owners to ensure they are fed a high-quality, nutrient-dense diet for the sake of their health. They may have shorter lifespans than your average pet, but you can help them reach their maximum life expectancy by knowing what diet is best for them.
