Can Rats Eat Grapes? [What About Their Seeds?]

Can rats eat grapes? If you have a pet rat, questions like this are probably constantly on your mind. Rats are known to be able to eat a large variety of different fruits and vegetables, but not all of the foods they eat are equally good for them. That’s exactly why it’s so important that before you feed your rat a new food, you check if they can safely consume it. After all, you want your pet rat to be healthy and happy, and that starts with a good diet.

Today I’m going to go over everything you need to know when it comes to giving grapes to your rat. I will go over whether or not they can eat this fruit, if they can eat the seeds, and much more in an effort to give the most complete answer to this question.

I highly recommend you read the entire post, but if you’re in a hurry and need a quick answer, here it is: Rats can definitely eat grapes. They’re a great fruit to include in their diet and studies have shown that they offer many benefits to your rat. They’re rich in antioxidants, vitamins, minerals, and fiber while being low in fat. Do make sure to wash them properly to remove any pesticides.

What’s in a grape?

Grapes have been cultivated for thousands and thousands of years, starting around 6,000 years ago in the Near East. I’m not going to bore you with a complete history of the fruit, but what I am going to do is briefly go over what nutrients this fruit is composed of. That way, we can get an idea of what we’re putting in our rat’s mouth.

A cup of grapes contains the following macronutrients:

  • 27.3 grams of carbs
  • 1.4 grams of fiber
  • 104 calories
  • 1.1 grams of protein
  • 0.2 grams of fat

On top of that, grapes are an excellent source of vitamins C, K, and B6. They’re also rich in Thiamine, Copper, Manganese, and Potassium.

Benefits of feeding grapes to rats

Grapes contain resveratrol, which is great for your rat. Studies on rats have shown that this compound improved the animal’s learning, mood, and memory. Especially in older rats this is a huge benefit.

In addition, the same study showed that it increased blood flow to their brain and showed signs of increased growth. Rats are highly intelligent animals, so anything that’s good for their brain is great for these animals.

Furthermore, grapes are great for your rats bones. It’s been scientifically proven that grapes improved bone density.

And if that wasn’t enough, yet another study has shown that it also helps against inflamed bowels and increases the blood levels of anti-inflammatory compounds.

On the whole, grapes offer tons of benefits for rats and you should definitely consider feeding them this fruit.

Are grapes toxic to rats?

Fortunately, this fruit is not toxic to rats at all and wild rats eat them all the time. Nevertheless, moderation is key. Do not dump a whole boatload of grapes in your rat’s cage. Always make sure that they have a balanced and varied diet that contains many different kinds of fruits, vegetables, and pellets.

Furthermore, you should make sure that you wash the fruit properly before giving it to your rat. The skins can have pesticides on them which are of course not good for your rat. Washing in a mixture of baking soda and water is recommended, but washing it under cold water for a couple of minutes will also do.

Unlike some other fruits, such as apples, the seeds in grapes are not toxic to rats. Nevertheless, they do not contain any nutrition so most rats will not eat them and just toss them aside. You can choose to buy the seedless variety, but that’s not a necessity. There’s also no need to peel the grapes first. As long as you’ve properly washed the skins, there’s no risk there and most rats will not even eat the skins anyway.

Another thing to note is that these fruits are quite high in sugars. In small quantities, this is not such a big deal, but you should take care not to overfeed your rat.

What kind of grapes can rats eat?

Grapes come in many different varieties, but the most common ones are white (also known as green) and red. Rats can eat this fruit in all their varieties, but red grapes have notably higher antioxidant levels and are therefore considered to be the healthier option.

However, that does not mean that white grapes are bad. They have fewer antioxidants than their red counterpart, sure, but they’re still rich in many other nutrients.

Can rats eat raisins?

Raisins are pretty much just dried out grapes. Rats can eat them, but raisins are even higher in sugar than grapes. For that reason, make sure that you do not feed them too many.

Do rats enjoy eating grapes?

Most rats absolutely love grapes. The best way to find out if your rat is among those is by simply putting some of this fruit in front of them and see how they react. There’s a very high chance that he will devour it love it. One of my favorite things about rats is that they can eat such a wide variety of foods and that they all have their own likes and dislikes. This makes feeding them an absolute joy. It’s always a lot of fun to discover what your rattie likes and it’s a good bonding experience.

Nevertheless, there is a chance that your rat will not enjoy this fruit. If so, there’s nothing to be worried about. As I’ve said, not all rats like the same foods.

Alternative foods

If your rat doesn’t seem to be particularly interested in grapes there are plenty of other food options for them. They’re omnivorous and can eat almost anything so there’s no need to be upset if they don’t like a particular food.

I’ve written a complete list of what fruits rats can eat, which you can find here. The post I’ve linked to also contains important information on what rats can not eat (such as blue cheese, which is poisonous to rats), so I recommend checking it out to avoid feeding your rats the wrong foods.
