Why Do Cats Act Weird When Scratching the Base of Their Tail? 10 Reasons

It’s not uncommon for cats to act weird when you scratch the base of their tail. In fact, this behavior is so common that it’s often referred to as the “tail up” response. While the exact reason for this behavior is unknown, there are a few theories that could explain it.

The 10 Common Reasons Why the “Tail Up” Response Happens

1. They Feel Threatened

One theory is that the tail-up response is a defensive reaction. When a cat feels threatened, their natural instinct is to protect themselves. By arching their back and raising their tail, they are making themselves appear larger and more intimidating to whatever is causing them to feel threatened.

2. They Love You

Another theory is that the tail-up response is a sign of affection. When you scratch a cat in just the right spot, it can be incredibly pleasurable for them. Much like humans, cats enjoy being touched in a way that feels good, and the base of the tail is a particularly sensitive spot for many cats. As a result, when you scratch them there, they may respond by raising their tail as a way of showing their enjoyment.


3. They’re Ticklish

The most common reason for your cat to act weird when you scratch their lower back is that your kitty may be ticklish. Just like humans, some cats have sensitive areas that can produce an involuntary reaction when touched. So, if your cat starts squirming or kicking their legs when you scratch them there, it’s likely because they’re ticklish.

4. They’re Communicating

Another possibility is that your cat is trying to tell you something. Cats communicate through body language and scratching the base of their tail may be a way of telling you that they’re uncomfortable or in pain. If you notice your cat doing this along with other signs of distress, such as meowing loudly or hiding, it’s best to take them to the vet to rule out any medical reasons for their behavior.


5. They’re Happy

Some cats simply enjoy the sensation of being scratched in that spot. Cats have a lot of nerve endings in their tails, so scratching or rubbing this area can feel good to them. If it feels good to them, they may start purring or leaning into your hand to signal that they’re enjoying it. It’s like a good massage! Use this time to feel for any lumps, bumps, cuts, bruises, and body changes.

That’s incredibly useful information to have as a pet owner! You can even keep a log if you want to track body condition over the years.

6. They’re in Heat

If your female cat is acting weird when you scratch the base of her tail, it could be because she’s in heat. Cats in heat often behave differently than usual, and they may become more affectionate or even aggressive. If you think your cat is in heat, it’s best to take her to the vet to confirm and get guidance on how to proceed. They’ll likely recommend you spay your cat to prevent any unwanted pregnancies.


7. They’re Overstimulated

Scratching the base of your cat’s tail can also lead to overstimulation. Cats are very sensitive creatures, and too much stimulation in one area can make them feel uncomfortable. If you notice your cat getting agitated or start swatting at you when you scratch their lower back, it’s best to stop and give them a break.

8. They’re Marking You as Theirs

Another possibility is that your cat is marking you as their territory. When cats rub their bodies against you, they’re leaving their scent on you. This is a way of claiming you as their own and letting other cats know to stay away. If your cat does this often, it’s a good sign that they consider you to be a part of their family!


9. They’re Stretching

Cats often stretch after a good nap, and this may be why your cat acts weird when you scratch the base of their tail after they’ve just woken up. When they wake up from a nap, their muscles are likely to be stiff and sore. By stretching, they’re loosening up their muscles and getting rid of any knots.

10. They Have an Itchy Spot

It’s also possible that your cat has an itchy spot that you’re unknowingly scratching. This could be caused by a number of things, such as fleas, allergies, or even just dry skin. If you think your cat may have an itchy spot, it’s best to take them to the vet to get checked out. They can provide you with medication or other treatment options to help relieve your kitty’s itchiness.
