How Do Cats Tails Work?

Cats use their tails for balance and body-temperature regulation. Cats also use their tails for communication, but the messages can get lost in translation.

What is my cat’s tail telling me? A puffed-up tail says, “I’m scared,” a low, straight tail says, “I’m ready to attack” and a vertical tail says “Hello, I’m pleased to see you!”. If a cat wraps their tail around you, this is a sign of trust. And If a cat swishes their tail from side to side, they are probably deep in concentration.

Cats all behave differently. Tail language in cats doesn’t always fit with these guidelines. To understand what your cat’s tail movements mean, you should look at your cat’s entire body language.

Why Do Cats Have Tails?

The tail is an integral part of the cat’s anatomy. The tail is often referred to as the “fifth limb.” So, why is a cat’s tail so important? Well, it has three functions:

  1. Communication – Cats use their tails to communicate with other animals and people. They can express feelings such as fear, anger, trust, or contentment with their tail. Cats can also scent-mark using the scent-glands at the base of their tail.
  2. To Regulate Temperature – Cats with bushy tails, such as Maine Coon, can cuddle their tail to keep warm. Cats originating from hot climates, such as Siamese, have very thin tails that help them to stay cool.
  3. Balance – The cat’s tail is vital for stability, especially when jumping.

Learning more about your cat’s tail can help you to understand their behavior.

What Is a Cat’s Tail Made Of?

It may look like a tube of fur, but the cat’s tail has a complex structure. The tail is made up of 18-23 bones. The bones are larger at the base of the tail and gradually get smaller towards the tip.

Each small bone is surrounded by 6 layers of muscle on each side. This allows the cat to flex, extend, and swish their tail.

The base of the tail is connected to the cat’s lumbar spine, and lots of tail movements are controlled by muscles in the lumbar spine. This means spinal injuries can impact tail mobility.

Why Does My Cat’s Tail Twitch When I Touch It?

If you lie down next to your cat and touch her tail, you’ll probably notice it start to twitch. This is an automatic reflex that helps to protect the tail.

This is like the response humans have when their limbs are touched. Imagine you are sitting with your legs straight out in front of you, and someone unexpectedly touches your shin. You’d probably recoil your leg (to protect it).

Because a cat’s tail is positioned behind them, they can’t see what is happening to it. So, it’s no surprise cats have developed such strong tail reflexes. This explains why your cat’s tail twitches every time you touch it.

It can be tempting to play with a cat’s tail, but your cat will quickly become irritated if you do this.

What Cat Tail Movements Mean

There is plenty of information out there. Although this information can be helpful, it cannot provide definitive answers because all cats are unique.

The following “tail language” tips can be used as a starting point for understanding your cat’s behavior. However, tail movements often have multiple meanings – something we will explore below. Also, it’s essential to consider your cat’s entire body language, not just their tail movements. Here are some tips to help you understand your cat’s behavior:

Cat’s Tail Standing Tall

When a cat’s tail is vertical, this usually means they are happy to see you. Muscles in the cat’s lumbar spine initiate this tail movement.

According to Science Direct, cats perform this “tail up” behavior when:

  • They are greeting their mother (as kittens).
  • They are greeting another cat (usually a cat with higher social status) in a friendly way.

In a domestic setting, your cat is probably saying something like “hello!” “play with me” “feed me” or “I am happy to be around you.”

If your cat is rubbing her face on you, or rubbing the base of her tail on you, this is further evidence that she is greeting you. Also, cats sniff each other during a friendly greeting.

So, if your cat’s tail straight up in the air, she’s rubbing against you, and sniffing you, she must be feeling happy and content.

Cat’s Tail Tall and Vibrating

If your cat’s tail is upright and vibrating, she is probably very excited. Some cats do this when they know dinner is about to be served. Cats’ tails may also vibrate after they’ve smelled catmint or eaten something delicious like tuna.

If your cat’s tail is low and vibrating, your cat may also be excited, but a low tail is more often a sign of fear or anger. If the tail is down and thrashing, this suggests the cat is very irritated and is about to pounce.

Cat’s Tail Low and Straight

If your cat’s tail is low and sticking straight out behind her, she probably feels threatened. Cats tend to keep their tails low and straight if they are unsure about a situation.

This may be because it is easier to jump or pounce from a tail-down position. Keeping their tails down also helps them to hide from predators.

However, a tail-down position does not necessarily mean your cat feels threatened. Look for other cues to confirm this. Are your kitty’s eyes very wide? Are her ears pricked up? Is her body flattened? If so, she probably feels wary and suspicious.

Persian cats always keep their tails low (no matter their mood), so there are certainly exceptions to these rules.

Cat’s Tail Swishing from Side to Side

If your cat’s tail is swishing from side to side, she is probably concentrating on something. Cats tend to do this then they are stalking prey or watching something interesting out of the window.

If your tail is swishing her tail quickly, this suggests she is ready to pounce. It’s best not to pet your kitty when she is in “hunting mode.”

If your cat is concentrating on something that is outside the window, try to redirect her attention inside the home. It is crucial to play with your cat regularly to satisfy her desire to “hunt.”

Cats sometimes also swish their tail from side to side if they are overheated. If that’s the case, your cat will be lying down and showing signs of exhaustion. Make sure your cat has plenty of water and a cool place to sleep.

Cat’s Tail Between Legs

If your cat is standing on all fours, and her tail is swishing between her legs, she probably feels intimidated. Dogs also do this to show submission.

Animals hang their tails low so as not to draw attention to themselves. Having the tail in this position also helps to protect the most delicate part of their body.

Various factors can make a cat feel intimidated. Often, it’s because the home is too noisy, or there are too many pets (or people) around.

Cats may also put their tail between their legs if they are feeling sick or in pain. Falling sick makes them more vulnerable to predators, so they try to become inconspicuous by lowering their tail.

Cat Hugging Her Tail

If your cat is lying down and hugging her tail, she may be trying to stay warm. Breeds such as Maine Coon have long, bushy tails for this purpose. Cats may also hug their tails to feel protected.

Kittens can often be seen hugging their tails while they sleep. They may do this to stay warm, or it might be a self-soothing behavior (much like a baby sucks their thumb).

If your cat is continually hugging her tail while indoors, this suggests it’s more of a comfort thing, rather than a need to stay warm.  Check for any signs of stress such as patchy fur or weight loss.

Cat’s Tail Puffing Up

If your cat’s tail is puffed up like a bristle brush, this means they are terrified. Cats puff their tails up to look bigger in front of predators, so it’s a bad idea to touch your kitty when she’s in this state.

Cats with bristly tails are synonymous with Halloween. Most of us have seen these tails in comic strips, but we don’t see them much in real life. This is because cats only behave this way when they are petrified.

If your cat sees an aggressive dog, coyote, or another threatening animal – she may behave in this way.

According to some owners, cats may also puff up their tails when they have been stroked for too long (and have become overstimulated). If that’s the case, the fur tends to stand on end, but the cat’s body language remains quite relaxed.

There will be no hissing, spitting, etc., and the cat’s eyes will not widen. An overstimulated cat will usually walk away when they have had enough. That’s why it is important not to restrain your cat while stroking her.

Cats Tail Puffed Up at the Base

Sometimes, the fur at the base of the tail puffs up, but the rest of the fur remains flat. If your cat’s eyes are wide, and her body is also raised up at the same time, this is a clear sign of aggression. You should leave your cat alone and let her calm down.

If your cat gently lifts the base of her tail and rubs her bottom against your leg, this is different. This can be interpreted as a friendly greeting.

Cat’s Tail Moving While Sleeping

Cats sleep for around 16 hours a day. Sleep leaves cats vulnerable to predators, so they’ve learned how to protect themselves even while sleeping.

Cats are light sleepers and they use their tails to sense danger. If their tail detects a threat, this prompts them to wake up and run away.

If your cat is sleeping, but her tail is gently swishing, this suggests she’s in a light stage of sleep. If your cat always seems semi-alert while sleeping, try to reduce noise and stress in the household.

Cat’s Tail Wrapped Around Someone

According to some cat behaviorists, this is the ultimate sign of affection. When cats wrap their tails around other cats or humans, this can be compared to a hug. After all, a cat’s tail is very sensitive and they use it for balance, so placing their tail around someone else is a sign of trust.

If your cat blinks slowly in front of you, this is another sign of trust and affection.

How Do Cats’ Tails Help Them Balance?

According to NCBI, cats use their tails as a counterbalance when walking and jumping. In this experiment, cats had to walk across a narrow beam.

When the beam was tilted slightly to the right (forcing the cat’s body to the right), they stuck their tail out to the left to compensate. This stopped them from falling off the beam.

Cheetahs use their tail in this way when pouncing on prey. The tail helps them shift their weight quickly from side to side so they can corner their prey. Cats may do something similar when they catch mice.

What’s more, when a cat falls from a countertop or window, their tail may help them to land more effectively. Because the tail rotates in the opposite direction to the rest of the body in midair, this provides angular momentum, which sets the cat up for a better landing.

Do All Cats Have Tails?

Manx cats are born without tails (or with short, stubby tails). These cats originate from the Isle of Man. The tail-less gene began as a random genetic mutation. It spread quickly because the Isle of Man is a small island with limited breeding opportunities.

Manx cats can still function without a tail because they have slightly longer legs to compensate.

What Happens If a Cat Loses Its Tail?

Road accidents can sometimes lead to tail injuries. If the damage is severe, the cat’s tail may need to be removed.

If a cat loses its tail, they may struggle to jump at first, but they will usually adjust. Cats are incredibly adaptable creatures, and tail amputations don’t usually affect their quality of life.

The tail is an essential part of the cat’s anatomy because it is used for balance and social interaction. Although cats use their tails to communicate with humans, we don’t always understand what they are trying to say.

Use the above guidance to decode your cat’s behavior. Although you cannot know for sure how your cat is feeling, you can formulate a good guess by looking at her tail language.
