6 Reasons Why Your Cat is Losing Hair

Sudden hair loss can be very jarring for a cat owner. Any change in appearance can be alarming—but a sudden change in the fur pattern? That’s instant cause for concern.

Problematic hair loss is typically accompanied with licking, biting, gnawing, and scratching at the skin, an increase in hair balls, and other abnormalities such as redness, bumps, scabs, sores, or crusts. More severe symptoms can also include changes in appetite, vomiting, diarrhea, changes in energy levels, increased thirst and urination, or an enlarged abdomen or pot-belly appearance.

Acquired feline fur loss could be attributed to several factors, including:

Fungal or Parasitic Causes

Ringworms, mites, or flea allergies can cause fungal or parasitic infections in cats. Proper preventative measures should be taken to avoid them in both outdoor and indoor cats. But if such an infection occurs, topical ointments will likely be prescribed by a vet. Further, if there’s a secondary infection, IV fluids or antibiotics may be required.

Food Allergies

A cat can develop allergies to its food at any age, and the reaction can include a rash from developing on it’s skin. This rash is usually itchy and irritating to the cat. Conjunctivitis (pink eye), nasal and ocular discharge, and inflammation of the ears may also occur.

Changing diets and applying ointments can help relieve these symptoms. Your veterinarian can provide further guidance based on your specific cat’s situation.


Hyperthyroidism in cats is a condition where the thyroid glands, located in the neck, produce excessive amounts of thyroid hormones. The thyroid hormones play a crucial role in regulating the body’s metabolism. When there is an overproduction of these hormones, it can lead to a variety of symptoms, one of which is hair loss or alopecia.

Urinary Tract Issues

UTIs are often mistaken as behavioral problems over medical, so it’s often said that they are among the most misunderstood conditions in cats. However, they are often lifelong issues that require lifetime care. It’s important to get your cat treated as quickly as possible because UTIs can be just as painful for a cat as they are for humans.

Symptoms include accidents outside of the litter box, blood in the urine, yowling when urinating, frequent urination, and less frequent urination. Causes include stress, urethral plugs, feline idiopathic cystitis (FIC), and stones.

Depending on a cat’s diagnosis, a calming and enriching environment, specific medications, and urinary health cat food (which moderate the intake of calcium, phosphorous, and magnesium that can cause crystals to form in the urine) can be recommended or prescribed by your vet in order to help alleviate a cat’s UTI.

Dry Skin

This one is pretty self-explanatory. Just like how weather and environmental conditions can cause our skin to become irritated and cracked, the same thing can happen to a cat’s skin. And it can cause itchy and red rashes to form.


In terms of stress, if your cat otherwise appears healthy but is demonstrating excessive grooming, it could have displacement grooming. This is rooted in anxiety, and the grooming may serve as a calming mechanism for the cat. If the relationship between your cats is contentious, it may also be a way to deflect aggression from other cats.

If this is left untreated, it can turn into a condition known as “psychogenic alopecia,” which makes the grooming compulsive in nature. This type of alopecia generally occurs only on places that your cat can reach with its tongue—i.e., on the inner forelimbs, the rear area of the abdomen, the groin area, and/or the lower back area.

How to Help Your Stressed Cat

You can help your cat by purchasing perches and climbing posts to enrich its environment and offer privacy. Playing with your pet using interactive toys (and stimulating its instinct to hunt) is also a good way to distract them and help it burn energy. Food puzzle games, catnip, and nontoxic cat grasses can also aid in relaxation.

There are also products, like the Feliway diffuser, that releases a synthetic version of a cat pheromone, which is a calming chemical substance that a cat produces naturally. If these modifications are not successful, or if your vet decides that additional intervention is necessary, anti-anxiety supplements, medications, or special diets may be recommended. Such supplements could include Anxitane or Composure. If medicinal assistance is required, the drugs Fluoxetine or Paroxetine might be prescribed.
