Can Rats Eat Celery? [Can They Have The Leaves?]

Can rats eat celery? That’s a great question. Feeding your rat is usually not all that difficult – rats can eat many different kinds of food, including many different fruits and vegetables. Nevertheless, there are foods that are dangerous for them to consume and it’s great that you’re being a responsible rat owner and doing your research. Having a healthy rat starts with ensuring that they have a healthy diet.

In the wild, rats eat anything they can get their hands on. Even if it’s not good for them, they will still eat it. This is why it’s so important that you do the research and find out what is good, and what is not good for them to have. In today’s guide, I’m going to go over everything you need to know about feeding celery to your pet rat.

Luckily, I’ve got good news. Rats can eat celery but it’s not the best vegetable for them to eat. It does contain a decent amount of fiber and antioxidants but since it is made up almost entirely of water and doesn’t contain all that many other nutrients. There are many better vegetables that they can eat. Giving your rat some celery once in a while is not a problem, but it shouldn’t be a staple of their diet.

However, there’s much more to know about feeding this veggie to your rat! Keep reading and I’ll tell you everything you need to know for safe feeding.

Is celery dangerous for rats?

Celery is not dangerous for rats. The only risk is that your rat might get diarrhea if you feed them too much of it since the plant contains so much water.

There’s nothing in this vegetable that’s toxic to your rat. Some people mistakenly believe that because celery contains nitrates it’s carcinogenic. It’s true that celery is quite high in nitrate, but nitrate on its own is not carcinogenic.

It’s only when nitrate combines with amines that it forms nitrosamines which is a known carcinogenic. Luckily, celery contains a negligible amount of amines, so it’s not really something you need to be worried about.

The bigger issue with celery is that it is almost entirely made up of water and doesn’t contain many nutrients. It’s not particularly rich in vitamins and minerals when you compare it to other veggies.

Also, since it’s almost entirely made up of water it contains a negligible amount of calories. It’s true that too many calories will make your rat fat and is therefore bad, but rats do need calories for energy, and foods like celery that have almost no calories are therefore not the best option.

In fact, celery has so few calories that for a long time it was even considered a calorie-negative food. The idea of calorie-negative foods has since been debunked and proven to be a myth, but the point still stands that it contains a negligible amount of energy.

For these reasons, this vegetable shouldn’t be your first choice when it comes to feeding your rat. There are many other healthier alternatives available that your rat will benefit more from.

Feeding celery to rats

If you do want to give your rat some celery you have to make sure that you wash it thoroughly. Celery has been identified by the Environmental Working Group as being one of the vegetables with the largest amount of pesticides on it. These pesticides can be harmful to your rat, so make sure that you wash the plant thoroughly.

Research has shown that the most efficient way of getting rid of pesticides on vegetables is by soaking them in a mixture of baking soda and water. It’s a quick and convenient way to ensure that you get rid of most of the nasty stuff.

Once it’s been washed properly make sure to cut up the plant. Do not feed them a whole stalk. Rats are small animals and a single stalk is already too much for them.

Benefits of giving celery to rats

I’ve said before that celery is quite low in many nutrients. That’s true, it’s not very rich in vitamins and macronutrients, but it does have quite a lot of antioxidants and fiber.

Antioxidants are very important in fighting free radicals, and studies on rats have shown that due to their high antioxidant content celery can have varied healing effects. Also, the fiber in the plant will help aid your rat’s digestion.

So, while celery is not the greatest vegetable on the planet for your rat, it does offer certain benefits and giving your rat a little bit of celery once a week might be beneficial for them.

Final words: Can rats eat celery?

Yes, rats can indeed eat celery. However, this veggie’s high water content does not make it the most nutritious food for them.
