Can rats eat apples and is it good for them?

You’re probably familiar with the saying: “an apple a day keeps the doctor away.” But does the same apply to rats? We know now that rats can indeed eat apples, but is it actually healthy for them to do so, and should it be a regular part of their diet?

To find out, we’re going to take a closer look at what an apple contains, and how these nutrients can be of benefit to our pet rat.

According to Healthline, a medium-sized apple contains the following macronutrients:

  • 52 calories
  • 86% water
  • 0.3 grams of protein
  • 13.8 grams of carbs
  • 10.4 grams of sugar
  • 2.4 grams of fiber
  • 0.2 grams of fat

As we can see, apples are low in fat and calories while being high in sugar and fiber. The fact that apples are low in fat and calories is good because rats do not need all that much fat in their diet. Also, the relatively high amount of fiber found in this fruit is good for your rat’s digestion. However, since this fruit does contain a pretty high amount of sugar you have to be careful not to overfeed your rat. It’s fine as an occasional treat, but do not overdo it.

Apples also contain the important mineral potassium which studies have shown is important for muscle development in rats. Further, apples contain a good amount of Vitamin C. Even though rats are capable of synthesizing their own vitamin C (unlike humans, which can only get it from the foods they eat) they do still benefit from getting it in their diet.

So, we can conclude that apples are indeed a healthy addition to your rat’s diet and that they can benefit from eating them. However, you do have to be careful not to overdo it. The best results are achieved by feeding it to them as an occasional treat rather than making it a staple of their daily diet.

Can rats eat apple skins?

apple skins

Yes, rats can eat the peels of apples just fine. The skins are not dangerous for rats to eat and are actually the most nutritious part of the fruit. However, you do have to be careful that you wash the skins properly before feeding them to your rat. Especially if you have non-organic apples, there are often pesticides present on the skins. These pesticides are harmful to your rat.

A study by the University of Massachusetts has shown that the most effective way to get rid of pesticides is by soaking them in a mixture of baking soda and water for a few minutes and rinsing it with cold water after. In this study, the scientists used roughly 2 teaspoons of baking soda dissolved in 4 cups of water and soaked the apples for 15 minutes followed by a tap water rinse and it got rid of most of the pesticides.
