How Long Can Rats Live Without Food and Water?

Today we’re going to discuss how long rats can live without food and water. Food, water, and oxygen are the three main things that all living organisms on this planet need to survive. However, not all animals need the same amount or need it at the same frequency. Some animals can go for months without food or water, while others can only last for a few hours.

Part of being a responsible pet owner is making sure that your rat has access to plenty of food and water, but just for curiosity’s sake, you might be wondering how long your rat can actually survive without access to these necessities. Wonder no more, because, in this article, I’m going to answer every question you’ve ever had about how long your rat can live without food and water, let’s dig in!

How long can rats live without water?

how long can rats live without drinking water

For most animals, water is more important than food. It’s very common for many species to be able to survive for quite a long time without food, but only a very short amount of time without water.

In rats, this is quite a bit different. Rats can survive for a long time without access to a direct water source. In fact, rats can live for up to a month without directly drinking water! However, this does not mean that they can survive for a month without any fluids at all. The fact that they can live so long without directly drinking water is not because they do not need water, but rather because they get a lot of the fluids they need from the food they consume.

However, just because your rat can live for a long time without water does not mean that you can just leave their water bottle empty. Your rat depends on you to provide for him, so always make sure that you keep their water bottle filled.

So, as long as the rat has access to food, they can survive quite a while without drinking water directly. However, that doesn’t answer the question completely. After all, they might not be drinking water directly, but they’re still ingesting water through their food.

There’s not much data available on how long rats can survive without access to both food and water. Maybe this is for the best because, in order to find out, you’d have to conduct the cruel experiment of restricting both water and food from a rat until they die from starvation or dehydration.

Do rats drink water?

Rats might get a lot of their water intake from food, but that doesn’t mean that they do not drink water. In the wild, they usually drink from puddles or they drink the dew that accumulates on leaves or blades of grass. In captivity, they do not have access to these sources of water so you should provide it for them.

The ideal way to give water to your pet rat is through the use of a bottle rather than a bowl. The reason being that rats usually have trouble drinking from bowls, they often flip them over which results in all the water spilling on the floor. With a bowl, you will not have this problem, which is why it’s the preferred choice.

Also, rats are capable of drinking milk, and you can give them a small amount of milk on special occasions, but in general, it’s best to stick to water only.

how long can rats survive without food?

Now that we know that rats can live for quite a long time without water as long as they have access to food, you might be curious how long they can survive without food. The answer to this question is that rats can survive for a maximum of 4 days without eating anything, after that they will starve to death. The reason why they can not live without food for very long is mainly due to their quick metabolism.

Of course, the amount of time a rat can survive without access to food also depends on the rat in question. If the rat has a lot of body fat, they can survive for longer because they can burn the fat for energy whereas a skinny rat can not do so and will thus not last as long without food.

Also, just because your rat can survive a few days without food does not mean that this is something you should do. Your rat might not die from not eating for a few days, but since you should always keep rats in groups of at least 2 they might start attacking one another. They have very strong, sharp teeth and can easily kill each other. Starving rats are known to engage in cannibalistic behavior if the situation is dire enough. So if you do not feed your rats they might kill each other before they die from starvation.

On top of that, it’s simply inhumane to deny your rat food for long periods of time. They will get hungry, stressed, and anxious. These are intelligent animals and if you’re unable to properly feed them you’re not responsible enough to take care of one.
