Rats have tails, that’s something that almost everyone knows. Most people who do not own rats and never interact with them have misconceptions about their tails. They’re often perceived as cold, slimy, and gross appendages. However, any rat owner can tell you that this is not the case. Their tails feel much like your own skin and are a vital part of their anatomy.
Nevertheless, even among people who are familiar with rats, there are many questions surrounding these hairless appendages. For instance, do you know what their tail is used for, whether their tail can fall off, or why there is no fur on them?
All these questions, and more, will be answered in this post. Everything you’ve ever wanted to know about rat tails will be discussed, so buckle up, and let’s dig in.

Why do rats have tails?
There are 3 primary reasons why rats have tails: temperature control, balance, and communication. Let’s go over all of these reasons one by one in a little more depth.
The first reason why rats have tails is for temperature control. Their tail makes up only 5% of the surface area of their body but can dissipate around 17% of their body heat. This means that their tail is an excellent way for them to cool down when they’re too hot.
They do this by dilating and constricting the blood vessels they have in their tail. If they want to cool down, they dilate the blood vessels in their tail so blood will flow into their tail. The blood then cools down which reduces their internal temperature.
Vice versa, when a rat is feeling cold, it will constrict the blood vessels in their tail meaning less blood will flow into the appendage, and thus they will lose body heat.
The second reason why rats have tails is that it helps them to keep their balance. Rats climb a lot, and their tail helps them with that.
The way their tail helps them keep their balance is that it allows them to keep their center of gravity at the proper spot. For instance, if a rat is climbing on a rope it should keep its center of gravity right above the rope.
If he does not, he will not be able to climb it successfully because the rat and the rope will reach the moment of inertia, meaning that the rope will rotate and the rat will eventually fall off. Without a tail, they would be unable to maintain their balance, and thus they would be unable to climb difficult obstacles.
Rats are excellent climbers, and this is not in small part due to their tail.
The third reason why rats have tails is communication. However, it can be debated whether they have the tail for communication, or whether they simply use it for communication because they have it for the aforementioned reasons. After all, we sometimes use our hands for non-verbal communication but we probably don’t have hands for the purpose of communication, we simply use them for this purpose because we can.
An example of rats using their tails for communication is that rats may flick their tail from side to side when they’re anxious or stressed. However, they can also wag their tail when they’re happy, just like dogs.
This video gives a perfect demonstration of a rat wagging its tail. As you can see, it looks extremely relaxed and happy.
Can rats live without a tail?
Rats can live without their tail in captivity and in the wild. In captivity, they will survive just fine without a tail but in the wild, they will be at a severe disadvantage. I’ve already mentioned that rats need their tails for 3 important purposes: temperature control, balance, and communication. If they lose their tail in an encounter with a predator it means that they’re less effective at climbing and temperature control which makes their life significantly harder because it will be more difficult for them to get away from predators and to maintain proper body temperature.
Do rats have feelings in their tail?
Rats do have feeling in their tails. However, it’s not the most sensitive part of their body because their tail is quite scaly. It’s kind of comparable to how you can feel when someone touches your fingernail – it’s not sensitive, but you definitely notice it when someone is touching it.
Does holding a rat by the tail hurt it?
Yes, holding your pet rat by the tail hurts it and is not something you should do. While the tail itself is not very sensitive holding the animal by the tail puts a lot of pressure on the point where the tail connects to the rest of the body. This is painful for your rat and causes them a lot of stress.
Also, holding your rat by the tail can damage the tail. It can result in degloving of the tail which is a loss of skin and deep tissue in the tail.
What does a rat tail feel like?
When you see the tail of a rat it might look cold, slimy, and pretty gross. However, any rat owner can tell you that this is not the case! Rat tails feel much like our own skin – not slimy or gross at all. Also, since they use their tail to regulate their temperature the tail is not cold to the touch.
Can rats shed their tail?
There are quite a few lizards, such as the iguana, that are capable of shedding their tail in dangerous situations. You might wonder if rats can do the same.
There are some species of rats, such as the spiny rat and the dassie rat, that can shed the skin from their tail. They do not release their entire tail, but only the skin. They do this in order to facilitate an escape in dire situations. However, most rats, including your pet rat (Rattus Norvegicus) are not part of the species of rats that can shed their tail.
Do rat tails grow back?
Lizards that shed their tail do so because they can grow them back. Unfortunately, adult mammals, including rats, can not do the same. They can not grow back lost limbs. Once their tail is gone, it’s gone forever and it will never grow back.
Do rats have bones in their tails?
Rats definitely have bones in their tails. Click here for more information about the rat’s skeleton.
Why do rats not have fur on their tail?
Rats have fur all over their body, but not on their tail. Why is that? The reason why they do not have hair on their tail comes back to one of the reasons why they have a tail in the first place: regulating their body temperature.
As I’ve mentioned, they use their tail to regulate their body temperature by flushing it with blood which lowers their internal temperature. To do this effectively, they need the tail to be naked so that it can cool off faster. If their tail was covered in fur it would greatly diminish the efficacy of their tail as a way to regulate their temperature.
Why do rats chew on their tails?
A healthy and happy rat will not eat its own tail. However, there have been reports of rats gnawing and eating their own tail. The most common reason why they do this is boredom. If your rat does not have a stimulating environment with toys and cagemates they will become bored and depressed. This may manifest itself in them becoming destructive and destroying their surroundings. In extreme cases, it might even result in them chewing on their own tail.
If you notice that your rat is chewing or biting their own tail I highly recommend that you contact a veterinarian because that’s not normal behavior.
Why are rat tails scaly?
Rats have scales on their tail for protection. Their tail is an important appendage and protecting it is quite important because without it they have a much lower chance of surviving in the wild.
Are rat tails prehensile?
In case you don’t know what a prehensile tail is, it’s a tail that can be used to grab or hold objects. Many new world monkeys have prehensile tails, but rats do not have prehensile tails. Wikipedia classifies rats as animals that have partially prehensile tails because they can wrap their tail around objects after running around it. Also, they can use their tail to hang from objects (albeit for a very short time).
How do you clean a rat’s tail?
Rats are pretty clean pets but their tail is one part of their body that can sometimes get a little dirty. You can tell when the tail is dirty and needs to be cleaned by taking a look at the color: if it’s a darker color than normal it might be time to give it a wash.
Cleaning the tail of your rat is quite easy. Just use a solution of some soap and water, dip a piece of cloth in it and wipe down the tail. If the tail is very dirty you can also dip their tail in a lukewarm solution of water and soap.
If you’re going to clean your rat’s tail make sure to be cautious. You do not accidentally want to hold on to their tail, spook them, and then cause them injury.
