Why Is My Cat Losing Hair? Causes, Symptoms, and Treatment Options

Hair loss in cats, also known as alopecia, is a common problem faced by many pet owners. It’s important to know the causes and possible treatments for this condition to ensure the health and happiness of your furry friend.

In this article, you’ll learn 20 causes of why is your cat losing hair and also find out what symptoms to look out for and what treatment options are available.

Causes of Hair Loss in Cats

There are many reasons why a cat might lose its hair. Here are some of the most common causes:

Skin Allergies

Cats can get skin allergies from many things. These include certain foods, allergens like pollen or dust, and even materials like plastic or rubber.

Cats with skin allergies may itch, have redness, and lose hair, especially in areas where the skin is irritated. Treatment involves finding and avoiding the allergen. It also involves taking drugs to control the symptoms.

Poor Diet

A poor diet can lead to hair loss in cats. Cats need a balanced diet with the right mix of proteins, fats, and carbohydrates. They also need certain vitamins and minerals to maintain healthy skin and fur.

A diet that lacks these nutrients can lead to a dull coat and hair loss. It’s important to feed your cat high-quality cat food that meets all their nutritional needs.

Food Allergies

Food allergies in cats can cause many symptoms. These include stomach issues like vomiting and diarrhea, as well as skin problems like itching and hair loss.

Common food allergens for cats include certain proteins found in beef, dairy, fish, and chicken. Treatment involves an elimination diet to identify the allergen, followed by a diet that avoids the allergenic food.

Dry Skin

Dry skin in cats can lead to itching, flaking, and hair loss. This can be caused by environmental factors like low humidity, as well as underlying health issues.

Regular grooming can help keep your cat’s skin moisturized, along with a diet rich in omega-3 fatty acids. In some cases, a humidifier can also help.

Fungal Infections

Fungal infections, such as ringworm, can cause hair loss in cats. Ringworm is a contagious fungus that can cause circular patches of hair loss, along with redness and scaling of the skin.

Treatment involves antifungal drugs. You must also clean the cat’s environment well. This prevents reinfection.

Bacterial Infections

Bacterial infections can cause skin inflammation and hair loss in cats. These infections can occur as a result of an injury, an allergic reaction, or an underlying health issue that weakens the cat’s immune system. Treatment involves antibiotics to clear the infection.

Nutritional Deficiencies

Nutritional deficiencies can lead to hair loss in cats. Cats need certain nutrients for healthy skin and fur. These include protein, fats, and many vitamins and minerals.

A diet that lacks these nutrients can lead to hair loss. It’s important to feed your cat a balanced diet that meets all their nutritional needs.

Hormonal Imbalances Or Hyperthyroidism

Hormonal imbalances, such as those caused by hyperthyroidism, can result in hair loss in cats. A cat has hyperthyroidism when its thyroid gland makes too much thyroid hormone.

This can cause many symptoms, such as weight loss, hunger, and hair loss. In some cases, controlling thyroid hormone levels may require medication and surgery.

Urinary Tract Issues

Urinary tract issues can cause discomfort and stress in cats, which can lead to over-grooming and subsequent hair loss. These issues can include urinary tract infections and bladder stones.

They can also include feline lower urinary tract disease (FLUTD). The treatment depends on the issue. It can include antibiotics for infections, dietary changes, and, in some cases, surgery.

Stress and Anxiety

Cats can lose hair due to stress or anxiety. This is often seen in cats who over-groom as a coping mechanism. Stress can be caused by a variety of factors, including changes in the cat’s environment, conflicts with other pets, and health issues.

Treatment involves finding and managing the source of stress. It also involves using therapy and, in some cases, anti-anxiety drugs.

Over-Grooming

Over-grooming can lead to hair loss in cats. This can be a sign of underlying issues such as stress, anxiety, or skin irritation. Treatment involves fixing the main issue. It also involves adding enrichment. In some cases, it uses anti-anxiety drugs or pheromone diffusers to reduce stress.

Autoimmune Disorders

Autoimmune disorders can cause a cat’s immune system to attack its own hair follicles, leading to hair loss. The conditions can be hard to diagnose and treat. They often need immunosuppressive drugs.

Cancer or Tumors

In some cases, hair loss can be a sign of cancer or tumors. If you notice any lumps or bumps on your cat’s skin, it’s important to seek veterinary care immediately. Treatment can involve surgery, chemotherapy, or radiation, depending on the type and stage of cancer.

Cancer Treatments

Just like in humans, cancer treatments such as chemotherapy can cause hair loss in cats. However, unlike in humans, hair loss in cats due to chemotherapy is less common. If your cat is undergoing chemotherapy and you notice hair loss, it’s important to discuss this with your vet.

Some Medications

Certain medications can cause hair loss as a side effect. If you notice your cat losing hair after starting a new medication, it’s important to consult with your vet. They may be able to adjust the dosage or switch to a different medication.

Poison or Toxins

Exposure to certain poisons or toxins can cause hair loss in cats. This can include certain plants, household cleaners, and even some types of flea and tick treatments. If you suspect your cat has been exposed to a poison or toxin, it’s important to seek veterinary care immediately.

Fleas

Fleas are a common cause of hair loss in cats. The itching caused by flea bites can lead to excessive scratching and hair loss. Regular use of flea prevention products can help keep your cat flea-free.

Lice

Lice can cause itching and discomfort, leading to hair loss in cats. If you notice small, white specks in your cat’s fur or around their ears, it could be a sign of lice. Treatment involves special shampoos or sprays that kill lice.

Mites

Mites can cause a condition known as mange, which can lead to hair loss in cats. Mites are tiny parasites that burrow into the cat’s skin, causing itching and irritation. Treatment usually involves medicated shampoos or dips. You also need to clean the cat’s environment to stop reinfection.

Atopy

Atopy, or environmental allergies, can cause itching and hair loss in cats. Common environmental allergens for cats include pollen, mold, dust mites, and certain fabrics. Treatment involves avoiding the allergen, along with medications to control the symptoms.

Symptoms of Hair Loss in Cats

If your cat is losing hair, you might notice the following symptoms:

Bald patches or areas

Bald patches or areas on your cat’s body are a clear sign of hair loss. These patches may appear or increase in size over time. They can occur anywhere on the body but are most found on the back, abdomen, or legs. The skin in these areas may appear normal or may be red, inflamed, or scaly.

Redness or inflammation

Redness or inflammation on your cat’s skin can indicate a skin condition causing hair loss. This can be due to an allergic reaction, infection, or irritation from excessive grooming. The skin may feel warm to the touch and may be painful for your cat.

Itching or scratching

If your cat is constantly itching or scratching, it could be a sign of a skin condition causing hair loss. This can be due to allergies, parasites, or skin infections. Excessive scratching can lead to further skin damage and hair loss.

Excessive shedding

While some shedding is normal, excessive shedding can be a sign of hair loss. This can be due to a variety of factors, including stress, poor nutrition, or underlying health conditions. You may notice more hair than usual on your furniture, clothing, or around your home.

Hairballs

Frequent hairballs can be a sign that your cat is losing more hair than usual. Hairballs happen when your cat swallows hair while grooming. The hair then builds up in the stomach and is vomited up.

While occasional hairballs are normal, frequent or large hairballs can be a sign of excessive hair loss.

Changes in appetite or energy levels

Changes in your cat’s appetite or energy levels can be a sign of an underlying health issue causing hair loss. For example, a cat with hyperthyroidism may eat more but still lose weight and hair. A cat with kidney disease may eat less and also experience hair loss.

Increased thirst or urination

Increased thirst or urination can be a sign of a medical condition such as diabetes or kidney disease, which can cause hair loss. If you notice your cat drinking or urinating more than usual, it’s important to seek veterinary care.

Enlarged abdomen or pot-belly appearance

An enlarged abdomen or pot-belly appearance can be a sign of a hormonal imbalance, which can cause hair loss. This can be due to conditions such as Cushing’s disease or hypothyroidism. These conditions often need medical treatment to manage.

Diagnosis and Treatment of Hair Loss in Cats

If you suspect your cat is suffering from hair loss, it’s important to seek veterinary care. The diagnostic process may include:

Physical examination

Your vet will perform a physical examination to check for signs of hair loss and other symptoms. This may include checking your cat’s skin for signs of inflammation, parasites, or abnormalities. The vet may also examine your cat’s health to look for signs of underlying conditions that could be causing the hair loss.

Blood tests

Blood tests can help identify underlying health issues that may be causing hair loss. These tests can check for conditions such as hyperthyroidism, diabetes, or kidney disease. They can also check for signs of infection or inflammation.

Urinalysis

A urinalysis can help detect urinary tract issues that may be causing hair loss. This test involves analyzing a sample of your cat’s urine for signs of infection, crystals, or other abnormalities.

Skin scrapings or biopsies

Skin scrapings or biopsies can help identify skin conditions or infections causing hair loss. This involves taking a small sample of your cat’s skin and examining it under a microscope.

Topical creams or ointments

Topical creams or ointments can help treat skin conditions causing hair loss. These medications can help soothe inflammation, treat infections, or relieve itching.

Oral medications

Oral medications can help treat underlying health problems that cause hair loss. These can include antibiotics for infections, hormone therapies for endocrine disorders, or anti-inflammatory medications for allergies.

Flea and tick prevention

Flea and tick prevention can help prevent hair loss caused by flea bites. You can use a topical flea and tick product. Or, you can give your cat a flea and tick collar. You can also give a flea and tick preventative medication.

Dietary changes

Dietary changes can help address nutritional deficiencies causing hair loss. This may involve switching to high-quality cat food. You could give your cat a supplement and feed a prescription diet recommended by your vet.

Stress reduction techniques

Stress reduction techniques can help manage hair loss caused by stress or anxiety. This may involve giving your cat a quiet, comfy space. You can also use pheromone diffusers and give your cat toys or activities.

Anti-anxiety supplements or medications

Regular grooming

Regular grooming can help keep your cat’s skin and fur healthy, preventing hair loss. This may involve brushing your cat to remove loose hair and prevent mats. You should also check your cat’s skin for signs of pests or problems. You may also need to bathe your cat with a gentle shampoo.

Flea and tick prevention

Flea and tick prevention can help prevent hair loss caused by flea bites. Regular use of flea prevention products can help keep your cat flea-free.

Monitoring for signs of hair loss

Keep an eye on your cat’s grooming habits and look for signs of hair loss. If you notice any changes, it’s important to seek veterinary care.

Adjusting dietary or environmental factors

If your cat is losing hair due to a poor diet or environmental stressors, making adjustments can help. This may involve switching to better cat food. You could also use a humidifier to raise humidity at home. Or, you could cut your cat’s exposure to allergens.

Providing stress-reducing measures

Providing a calm and comfortable environment can help reduce stress and manage hair loss. This may involve giving your cat a quiet place to rest. Also, using pheromone diffusers to reduce stress. Or giving your cat toys or activities.

Consulting a veterinarian for guidance

If you’re unsure about how to manage your cat’s hair loss, consult with a veterinarian for guidance. They can provide you with advice tailored to your cat’s specific needs and circumstances.
