Why is my cat getting stripes?

Have you ever taken a second look at your cat and noticed some new stripes? Don’t worry, you’re not seeing things. While cats are famously known for their solid-colored coats, it’s not uncommon for felines to develop stripes or spots.

But what’s the reason behind your cat’s new stripes? The answer lies in genetics. Some breeds, like tabbies or Siamese cats, already have stripes in their genes. However, other cats can develop them due to random mutations. Certain genes responsible for pigmentation may activate or deactivate, causing stripes to appear out of nowhere.

Age is another factor that can contribute to a cat’s stripes. Kittens may have faint stripes that disappear as they grow older and their coat becomes more solid in color. Conversely, older cats may develop stripes as their coat starts losing pigmentation and changes with age.

So if you’re a cat owner who has recently noticed some fresh new stripes on your furry friend, don’t fret. It’s simply a genetic quirk or the result of aging that adds some unique charm to your pet’s appearance. In fact, many cat owners adore the added personality and spunk that stripes bring to their feline’s look.

Genetics: Certain Breeds of Cats Have Stripes

Well, it all comes down to genetics. The agouti gene is the key player in determining whether or not a cat will have stripes. This gene controls the distribution of pigment in a cat’s fur, resulting in the alternating bands of lighter and darker fur that create the distinctive tabby pattern. The thickness and color of the stripes can vary depending on the cat’s genetic makeup.

One of the most recognizable breeds with stripes is the tabby cat. Tabby cats have a distinctive M-shaped marking on their forehead, and their bodies are covered in stripes that can range from thin to thick. But tabby cats aren’t the only breed with stripes. Other breeds include the Bengal cat, which has bold, black stripes on a light-colored background, and the Egyptian Mau, which has distinctive spots and stripes on its coat. The Ocicat is another breed with a spotted coat that resembles that of an ocelot.

However, it’s worth noting that not all cats with stripes are purebred. Many domestic shorthair cats can also have tabby markings due to their mixed genetic heritage. The likelihood of a cat having stripes increases if they come from a breed known for their striped coat.

While pseudogeny can cause some cats to develop stripes, it’s important to recognize that sudden stripe development in your cat could be a sign of an underlying health issue. Stress-induced alopecia, thyroid problems, and hormonal imbalances are just a few examples of health issues that may cause your cat to develop stripes.

Pseudogeny: A Genetic Mutation That Causes Striping

What exactly is pseudogeny? Simply put, it’s a genetic mutation that turns off the gene responsible for producing pigment in a cat’s fur. Instead of growing in a solid color, the fur grows in a striped pattern, creating an eye-catching and unique coat.

It’s important to note that pseudogeny is relatively rare and not found in all cat breeds. It’s most commonly observed in domestic cats, but it has also been seen in some wild cat species such as tigers and leopards.

However, not all striped cats have this genetic mutation. Some cats may have stripes due to selective breeding or natural variations in coat coloration. It’s also worth noting that if your kitty suddenly develops stripes, it could be a sign of an underlying health issue like stress-induced alopecia or hormonal imbalances.

But don’t worry. Pseudogeny isn’t harmful to your cat’s health and doesn’t require any special treatment or care. Their stripes will simply be a unique and distinguishing feature of their appearance.

Stress-Induced Alopecia: Hair Loss and Striping

This condition is caused by excessive grooming and licking due to stress and anxiety, which can cause the hair to break and fall out, resulting in patchy hair loss or striping.

Cats that live in multi-cat households, experience changes in their environment or have experienced trauma or abuse are more prone to stress-induced alopecia. Indoor cats are particularly susceptible as they have limited space and may not have enough stimulation or exercise.

Symptoms of stress-induced alopecia include patchy hair loss, striping on the legs or stomach, and excessive grooming and licking. If left untreated, the condition can lead to skin irritation, infections, and further hair loss.

The good news is that there are ways to treat stress-induced alopecia. The first step is reducing stress and anxiety in your cat’s environment. This can be done by providing a safe space for your cat to retreat to, increasing playtime and exercise, and reducing exposure to stimuli that cause anxiety. In some cases, medication may also be prescribed by a veterinarian.

It is crucial to act quickly if you suspect your cat is suffering from stress-induced alopecia. By recognizing the symptoms and seeking prompt treatment, you can prevent further complications and ensure your furry friend is happy and healthy.

To summarize, stress-induced alopecia is a common condition among cats that can lead to hair loss and striping. Reducing stress and anxiety in a cat’s environment is key to treating this condition. Here are some tips:

  • Provide a safe space for your cat to retreat to
  • Increase playtime and exercise
  • Reduce exposure to stimuli that cause anxiety
  • Consult with a veterinarian if necessary

Thyroid Problems or Hormonal Imbalances

While this may seem like a harmless quirk, it could be a sign of something more serious – thyroid problems or hormonal imbalances.

The thyroid gland is responsible for regulating metabolism, energy levels, and body temperature through the production of hormones. If this gland isn’t functioning correctly, it can cause significant health issues, including changes in your cat’s coat color and pattern.

Hyperthyroidism is a common thyroid problem that occurs when the gland produces too much hormone. This condition can cause thinning of the fur, leading to a sparser pattern and visible skin. The result? Stripes on your beloved pet. On the other hand, hypothyroidism occurs when the thyroid gland produces too little hormone, causing thicker fur which can lead to matting and clumping, resulting in striped fur.

But wait – there’s more. Other hormonal imbalances can also cause cats to develop stripes. For example, Cushing’s disease results in excess cortisol hormone production that leads to hair loss and skin discoloration. Addison’s disease is another hormonal condition that can cause changes in a cat’s coat color or pattern.

If you spot any changes in your cat’s coat color or stripes, it is essential to consult with your veterinarian for proper diagnosis and treatment. A thorough examination can determine whether there are any underlying health issues that are causing the changes. Diagnostic tests such as blood work can be done to confirm the diagnosis and guide treatment.

Signs to Look Out For in Your Cat

There are some telltale signs to look out for that could indicate an underlying health issue.

Changes in Fur Texture or Color

Your cat’s fur can tell you a lot about their health. If you notice patches of fur that are thinner or lighter than usual, this could indicate anemia or hyperthyroidism. On the other hand, if your cat’s fur is getting thicker or darker, this could be due to an increase in melanin production caused by a variety of reasons.

Changes in Behavior

Cats are known for being independent and aloof creatures. However, if your cat suddenly becomes more aggressive or lethargic, it could be a sign of an underlying health issue. Additionally, if your cat seems to be in pain or discomfort, they may vocalize more than usual or avoid certain activities.

Changes in Appetite and Hydration

Your cat’s eating and drinking habits can also provide clues about their health. If your cat is eating and drinking less than usual, this could be a sign of kidney disease or dental issues. Conversely, if your cat is consuming more food and water than usual, this could be a sign of hyperthyroidism or diabetes.

Other Signs to Look Out For

Aside from the above signs, there are other changes to watch out for. This includes weight loss, vomiting, diarrhea, and coughing or sneezing.

Diagnosis and Treatment for Stripes on Cats

If you notice stripes on your cat’s coat that seem unusual or out of place, it’s important to take action and seek veterinary care if necessary. Diagnosing and treating stripes on cats can be a complex process, as there are many potential underlying causes.

One common culprit of stripes on cats is ringworm, a fungal infection that can cause circular patches of hair loss and may result in the appearance of stripes on a cat’s coat. Other skin conditions, like allergies or flea infestations, can also lead to changes in a cat’s coat pattern.

When seeking veterinary care for your cat’s striped coat, your veterinarian will likely conduct a thorough physical examination and may take skin scrapings or hair samples for testing. Depending on the underlying cause, treatment options may include topical or oral medications, dietary changes, or lifestyle adjustments.

It’s important to note that not all stripes on cats require treatment. Some cats have natural coat patterns that include stripes or other markings, which can be perfectly normal and healthy. However, if you notice sudden changes in your cat’s coat pattern or if your cat appears to be experiencing discomfort or skin irritation, it’s crucial to seek veterinary care to determine the underlying cause and appropriate treatment plan.

Prevention of Stripes on Cats

Sometimes, we may notice stripes on their coats that don’t seem to belong. These stripes can be caused by various factors, including genetic predisposition, environmental stressors, or underlying health conditions. But fear not, there are steps that you can take to prevent the formation of stripes on your cat’s coat.

  • Balanced and Nutritious Diet: A healthy diet is crucial in preventing stripe formation. A lack of certain vitamins and minerals can lead to skin conditions that can cause stripes. Therefore, it’s essential to provide your cat with high-quality food that meets their nutritional needs. Make sure to consult with your veterinarian to determine the best diet for your cat’s specific needs.
  • Proper Hygiene: Regular grooming helps remove dead skin cells and promotes healthy blood circulation, reducing the chances of skin irritations that can lead to stripes. Brushing your cat’s coat also helps distribute natural oils, keeping their skin moisturized and healthy. Additionally, it’s crucial to keep your cat’s litter box clean to prevent any potential infections.
  • Stress-Free Environment: Cats are sensitive creatures, and exposure to stressors such as loud noises or changes in their routine can cause skin irritations that result in stripes. Providing them with a safe and comfortable space where they can retreat when feeling anxious or overwhelmed can help minimize stress levels. You can also use pheromone diffusers or calming sprays to help reduce stress and anxiety in your cat.
  • Regular Veterinary Check-Ups: Regular visits to the veterinarian can help detect any underlying health issues that could lead to stripe formation. Skin conditions such as allergies or hormonal imbalances may require medical treatment, and early detection and intervention can prevent further complications.

Tips for Caring for a Cat with Stripes

You may be wondering how to provide them with the best care possible. Striped cats are not a specific breed, but rather a common characteristic seen in many domestic cats.

To help ensure your cat is healthy and happy, it’s important to provide them with environmental enrichment and proper nutrition. Here are five tips for caring for your striped feline friend:


A cat’s coat is their pride and joy, and striped cats often have thicker coats than other breeds. Regular brushing can help prevent matting and remove loose fur, as well as keep their coat healthy and shiny. Additionally, trimming their nails regularly can prevent discomfort.

Environmental Enrichment

Striped cats tend to be active and playful, so providing opportunities for exercise is important. Consider providing toys, scratching posts, or climbing structures to keep them mentally and physically stimulated. Engaging in playtime with your cat is also an excellent way to bond with them.


A balanced diet is essential for all cats, but it’s especially important for those with stripes. They require high-quality protein sources to maintain their strong muscles, as well as a balanced mix of carbohydrates and fats for energy. Be sure to provide fresh water at all times and avoid overfeeding, which can lead to obesity.

Regular Health Checkups

Regular visits to the veterinarian are crucial for all cats, but particularly for those with stripes. They may be more prone to certain health issues such as obesity or skin problems, so keeping up with checkups and vaccinations is vital.

Love and Affection

Don’t forget that cats need love and affection just like humans do. Spend time cuddling with your furry friend or engaging in playtime together. Providing your cat with plenty of love can strengthen your bond and improve their overall wellbeing.


In summary, don’t panic if you spot stripes on your cat. It’s likely due to genetics, aging, or pseudogeny – a genetic mutation that turns off pigment production in a cat’s fur. While some feline breeds are predisposed to stripes, others can develop them through random mutations.

But be aware: sudden stripe development may indicate an underlying health issue such as stress-induced alopecia, thyroid problems, or hormonal imbalances. Keep an eye out for changes in behavior, appetite, hydration, fur texture or color and schedule regular veterinary check-ups.

To keep your striped kitty happy and healthy, provide environmental enrichment and proper nutrition. Regular grooming sessions will help maintain their coat’s appearance while exercise and playtime will keep them active.

A balanced diet with high-quality protein sources and fresh water at all times is essential – avoid overfeeding. And last but not least: show your furry friend plenty of love and affection because cats need it just like humans do.

In conclusion, don’t fret over stripes on your cat – embrace them.
