Why Is My Cat Losing His Hair?

Shedding is a natural process where cats lose old or damaged hair to make way for new growth. This process helps maintain the health of their coat and regulate body temperature. Shedding patterns can vary depending on the breed, age, health, and environment of the cat.

What Seasons are Cats Most Likely to Experience Hair Loss?

Cats usually experience more severe hair loss in the spring and fall. In the spring, cats shed their heavy winter coats and replace them with lighter summer coats to adapt to the warmer climate. In the fall, on the contrary, the cat will grow a thicker coat to ward off the coming cold winter. Hair loss can be more noticeable during the moulting process of these two seasons as cats shed a lot of their old hair. To alleviate the problem of flying hair in your home, cat owners can increase the frequency of brushing during the moulting period to help clean up the shedding hair and keep the home environment clean. At the same time, providing nutritionally balanced food will also help maintain the health of the cat's coat and reduce hair loss.

What Causes Hair Loss In Cats?

• Seasonal Hair Change

Cats will change their hair according to the seasons, especially in spring and summer and fall and winter, which is a normal physiological phenomenon.

• Skin Diseases

Skin conditions such as cat moss, flea allergies or mite infestations can cause inflammation of the skin, leading to hair loss in cats.

• Parasite Infestation

Parasite infestations such as fleas and mites can cause itchy skin, leading to frequent scratching and hair loss in cats

• Nutritional deficiencies

Lack of essential nutrients such as protein, essential fatty acids and vitamins can affect the health of the coat and lead to hair loss. 

• Allergic reactions

Cats may have an allergic reaction to certain foods or substances in the environment, which can cause skin problems and hair loss. 

• Endocrine problems

Abnormal thyroid function or other disorders of the endocrine system may affect the hair growth cycle and lead to hair loss. 

• Psychological factors

Psychological factors such as stress, anxiety or excessive hair licking may also lead to hair loss in cats. 

• Genetic factors

Certain cat breeds may carry the baldness gene, resulting in thinning hair. 

If your cat is experiencing unusual hair loss, it is recommended that you consult your veterinarian for diagnosis and treatment. Your veterinarian may recommend appropriate treatment options, including medication, improved diet, dermatologic treatment, or other targeted therapeutic measures. In the meantime, ensuring that your cat's living environment is clean and comfortable, and reducing stress, can help improve hair loss.

Which Skin Diseases Do Cats Exhibit Frequent Hair Loss?

Cats suffering from the following skin diseases usually show frequent hair loss symptoms:

• Ringworm

Ringworm in cats is a skin condition caused by a fungus that manifests as round or oval areas of hair loss accompanied by small, scaly flakes. This condition causes redness of the skin, sometimes accompanied by itching. Ringworm not only affects cats, but can also be transmitted to humans. 

• Parasitic infections

Parasitic infections such as fleas and mites (mange mites, ear mites) can cause cats to itch intensely, causing them to lick or scratch their fur excessively, which can lead to hair loss. Flea infections can also lead to black feces (“flea dirt”).

• Bacterial or yeast infections

These infections can cause redness, sores, flaking and itching of the skin, which can lead to hair loss. Bacterial infections may be caused by microorganisms such as Staphylococcus aureus or Streptococcus, while yeast infections are usually associated with a depressed immune system.

• Allergic reactions

Food allergies, environmental allergies or medication allergies can cause skin inflammation and hair loss in cats. Allergic reactions may be accompanied by skin erythema, papules or eczema.

• Endocrine diseases

Conditions such as hyperthyroidism or adrenocortical abnormalities (Cushing's disease) can also cause hair loss. These disorders affect hormone levels, which in turn affect the health of the skin and hair.

• Autoimmune skin diseases

Autoimmune diseases such as lupus erythematosus or vasculitis attack skin tissue, causing inflammation and hair loss.

If your cat is showing signs of frequent hair loss, you should contact your veterinarian for an examination so that the exact cause can be determined and appropriate treatment given. Your veterinarian may recommend skin scrapings, cultures, blood tests, or other diagnostic procedures to identify pathogens or evaluate potential internal health issues.

How to Know If My Cat is Seasonal Shedding?

Seasonal shedding is a natural physiological process in which cats adjust the thickness of their coats according to seasonal changes. In the spring, cats shed their thick winter coats to adapt to the upcoming warmer weather, while in the fall, cats grow thicker coats to ward off the cold. Below are some characteristics that distinguish whether a cat is in seasonal hair change:

• Time Regularity

Seasonal hair change usually occurs in spring and fall, which is the natural behavior of cats adapting to climate change.

• Characteristics of hair shedding

During the moulting period, the cat will shed a large amount of hair, which tends to be complete rather than broken or bald.

• Change in hair texture

As the seasons change, your cat's new growth of hair may vary; it may be finer and softer in the spring and denser in the fall.

• Behavioral changes

Cats may lick their fur more frequently due to the large amount of hair loss, which can sometimes lead to gastrointestinal problems such as trichotillomania.

• Hair Shine

During the moulting period, the cat's coat may lose its luster because it takes some time to synchronize the shedding of old hair with the growth of new hair.

• Distribution of hair loss

Seasonal moulting usually occurs throughout the body rather than being confined to one area.

If your cat displays the above characteristics and there are no other abnormal symptoms such as redness of the skin, uneven shedding or accompanied by dandruff, it is likely that it is experiencing seasonal moulting. If in doubt or concerned about your cat's health, it is advisable to consult your veterinarian for further examination and advice. 

When to See a Veterinarian

Consult a veterinarian if:

1.Sudden increase in hair loss

If the cat's hair loss is far above normal, it may indicate a health problem such as kidney disease or endocrine disorders. 

2.Hair loss in a specific area

If the cat's hair in a certain area is significantly reduced or falls off, it may be a sign of skin disease or parasitic infection. 

3.Hair loss accompanied by skin symptoms

If hair loss is accompanied by skin redness, itching, dandruff or wounds in the area of hair loss, this may be a sign of skin disease. 

4.Change in hair texture

If the cat's fur becomes dry, rough or oily, it may be a sign of malnutrition or a skin health problem. 

5.Behavioral changes

If your cat licks its fur excessively or scratches itself, it may be due to skin discomfort or pain. 

6.Decreased appetite or vigor

If your cat shows signs of loss of appetite or decreased vigor, this may be a sign of an internal health problem. 

FAQs

Can Knots in Cat Hair Lead to Shedding?

Knots in your cat's fur can indeed lead to shedding. When a cat's hair has not been properly groomed and cared for for a long time, the fibers between the hairs will gradually get tangled together and form clumps. These tangles will not only cause discomfort to the cat, but may also lead to skin damage, which in turn may cause hair loss. In addition, the knotted hair will restrict the normal breathing of the skin and hinder the distribution of sebaceous gland secretions, which originally help to lubricate and protect the hair, the lack of which will make the hair dry and fragile, and prone to breakage and shedding. 

When dealing with knotted hair, you should take a gentle approach and use a professional comb or knot-opening tool to avoid pulling hard enough to cause skin injuries. If the knots are severe, it may be necessary to cut off part of the hair to minimize stress and potential injury to the skin. In daily care, regular brushing of the cat's hair, providing balanced nutrition, maintaining environmental hygiene and regular bathing are effective measures to prevent knots and hair loss. If a cat's hair loss problem is accompanied by other skin symptoms such as itching, redness or dandruff, a veterinarian should be consulted promptly to rule out health problems such as skin disease.
