Wondering why is my cat shedding so much? You might notice more fur on your couch or clothes. Some shedding is normal, but sudden changes can mean something more. Take a look at these common causes:
Poor diet
Stress or behavioral issues
Age or hereditary conditions
Keep an eye on your cat shedding and their coat’s health. If you keep asking yourself, “why is my cat shedding?” you’re not alone.
Cat Shedding Causes

Seasonal Changes
You might notice your cat shedding more when the seasons change. This is normal for most cats. As temperatures drop, your cat grows a thicker coat for winter. When spring arrives, that thick fur comes off to make way for a lighter summer coat.
Cats living indoors may still shed a lot because of changes in sunlight and indoor heating.
Dry air inside can make your cat’s skin itchy, which leads to more fur loss.
Outdoor cats face cold air, which can also irritate their skin and affect how much they shed.
Shedding peaks during spring and fall, when cats switch between their winter and summer coats.
Veterinarians say, "Photoperiod is a key driver of seasonal shedding patterns in pets, with temperature also playing a role."
Here’s a quick look at how light and temperature affect cat shedding:
Evidence Type |
Description |
---|---|
Photoperiod Influence |
The length of daylight affects melatonin levels, which in turn influences hair follicle activity in cats. |
Temperature Role |
While daylight is the primary cue, temperature and humidity affect how shedding is perceived indoors. |
You will likely see the most fur around your home during these coat transitions.
Stress Factors
Stress can cause increased shedding in cats. You might not always notice when your cat feels anxious, but changes in their environment can trigger stress. Moving to a new home, adding a new pet, or even changing your daily routine can upset your cat.
When cats feel stressed, their bodies release a hormone called cortisol. High levels of cortisol over time can weaken the immune system and make skin problems worse. This can lead to excessive shedding or even bald spots.
Chronic stress raises cortisol, which can cause more hair loss.
Some cats may start over-grooming when stressed, pulling out their own fur.
You might see more fur on your furniture or notice your cat licking one spot over and over.
If you think stress is causing your cat’s shedding, try to keep their routine steady and give them a safe, quiet space.
Diet and Nutrition
What your cat eats plays a big role in their coat health. A poor diet can lead to dull fur and more shedding. Cats need plenty of protein and healthy fats to keep their skin and fur in top shape.
Nutrient |
Role in Coat Health |
---|---|
Protein |
|
Vitamins A, E, B12 |
Vital for regulating cell growth in hair and skin. |
Zinc |
Important for maintaining healthy skin and hair. |
Omega fatty acids |
Crucial for skin health; deficiencies can disrupt hair growth. |
You should look for foods with at least 45% protein from animal sources. Omega-3 and omega-6 fatty acids help reduce cat shedding and keep the skin healthy. If your cat’s diet lacks these nutrients, you may see increased shedding or a rough, patchy coat.
Health Issues
Sometimes, cat shedding points to a health problem. If you see bald spots, sores, or your cat seems itchy all the time, it could be more than just normal shedding. Many health conditions can cause excessive shedding:
Health Condition |
Description |
---|---|
Hyperthyroidism |
A systemic health issue that can lead to excessive shedding in cats. |
Diabetes |
Another systemic condition that may cause increased shedding. |
Allergies |
Can lead to excessive shedding due to skin irritation. |
Skin Infections |
Bacterial and fungal infections can impact the coat and cause shedding. |
Parasites |
Mites and fleas can cause scratching and increased hair loss. |
Neurologic Conditions |
May lead to over-grooming, appearing as excessive shedding. |
Other Diseases |
Includes kidney, liver, thyroid, adrenal gland diseases, and some cancers. |
If you notice sudden changes in your cat’s coat, or if they seem sick, talk to your vet. Early treatment can help prevent more serious problems.
Breed Differences
Some cats shed more than others because of their breed. Long-haired cats like Maine Coons and Norwegian Forest Cats have thick undercoats and lose a lot of fur during shedding seasons. Short-haired breeds, such as Siamese or Russian Blue, usually shed less.

Here’s a quick guide to how much different breeds shed:
Cat Breed |
Shedding Tendency |
FGF5 Genotype |
Additional Notes |
---|---|---|---|
Siamese |
Moderate |
L/L |
Sheds more during seasonal changes. |
Maine Coon |
Heavy |
l/l |
Requires regular grooming to manage shedding. |
Sphynx |
None |
N/A |
Hairless breed, does not shed. |
Bengal |
Moderate |
L/L |
Sheds during seasonal changes despite short hair. |
Ragdoll |
Moderate |
l/l |
Sheds during seasonal changes, regular grooming helps. |
Russian Blue |
Moderate |
L/L |
Sheds less than some breeds, weekly brushing helps. |
Long-haired and medium-haired cats need daily brushing to control cat shedding.
Short-haired cats usually need grooming once a week.
Hairless breeds like the Sphynx do not shed at all.
Dehydration
If your cat does not drink enough water, their skin can get dry and flaky. This leads to more cat shedding. Make sure your cat always has fresh water. Wet food can also help keep them hydrated.
Look for these signs of dehydration:
Dry, sticky, or tacky gums
Skin that does not spring back when pinched (loss of elasticity)
Sunken eyes or your cat seems tired
Less urination or changes in litter box habits
Keeping your cat hydrated helps their skin stay healthy and reduces shedding.
Excessive Shedding Signs
Normal vs. Excessive Shedding
You probably see cat hair on your couch or clothes every day. That’s normal. Healthy cats can lose between 100 to over 1,000 hairs per day. With about 60,000 to 120,000 hairs on their bodies, a little fur here and there is nothing to worry about.
But how do you know if your cat shedding is normal or if it’s something more? Here’s a quick way to tell:
Excessive Shedding |
|
---|---|
Hair falls out all over the body |
Hair loss in patches or certain spots |
No bald spots |
Bald spots or very thin areas |
More fur during spring and fall |
More fur than usual, plus itching or sores |
Normal shedding looks like a steady trickle of loose hair. You won’t see bald patches or skin problems. Excessive shedding means you find more hair than usual, and you might spot bald spots, itching, or changes in your cat’s behavior.
Warning Signs
Sometimes, cat shedding can signal a problem. Watch for these warning signs:
Bald patches or thinning fur in certain areas
More hair on your furniture or clothes than usual
Red, irritated, or flaky skin
Your cat scratching, licking, or biting the same spot over and over
Dull, greasy, or messy coat
Mats or clumps of loose hair
Changes in how shiny your cat’s coat looks
More dandruff than before
Tip: Your cat’s skin and coat show how healthy they are. If you notice a dull coat, lots of dandruff, or skin irritation, your cat may need help.
Cats that feel sick or stressed may stop grooming themselves. This can make their fur look messy or greasy. You might also see mats or clumps of hair. If you spot any of these signs, pay close attention.
When to See a Vet
You should call your vet if you notice any of these problems:
Bald spots or patchy hair loss
Itching, scratching, or biting at the skin
Redness, sores, or scabs
Skin irritation or swelling
Changes in your cat’s behavior or appetite
Weight loss or acting tired
If your cat loses fur in large clumps or seems uncomfortable, don’t wait. Some causes of excessive shedding, like allergies or infections, need quick treatment. Your vet can help find out what’s wrong and get your cat feeling better.
Note: It’s always better to check with your vet if you’re unsure. Early help can prevent bigger problems later.
Reducing Cat Shedding

Grooming Tips
Regular grooming is your best friend when it comes to managing excessive cat shedding. Brushing helps collect loose fur and keeps hairballs away. For long or medium-haired cats, daily brushing works best. Short-haired cats do well with brushing two or three times a week. Try using a rubber grooming mitt or a soft bristle brush for short coats, and a slicker brush or wide-tooth comb for longer fur.

Additional Tips |
|
---|---|---|
Short-Haired Cats |
2–3 times per week |
Use a rubber grooming mitt or soft bristle brush. |
Medium-Haired Cats |
More frequent brushing |
Prevent tangles and reduce shedding. |
Long-Haired Cats |
Daily brushing |
Use a slicker brush or wide-tooth comb. |
Bathing your cat every so often can also help, especially if your cat is shedding a lot. Some owners even use professional grooming services for extra help.
Diet Improvements
A healthy diet makes a huge difference in excessive cat shedding. Make sure your cat’s food has plenty of protein and natural sources of Omega-3 and Omega-6 fatty acids. Fish like salmon and sardines are great for this. Avoid foods with artificial flavors or additives. Supplements like Shed-X™ can also help improve coat health from the inside out.

Stress Reduction
Stress can lead to excessive cat shedding. Try to keep your cat’s routine steady. Give them quiet spaces and hiding spots. Calming products like pheromone diffusers can help. Cats in enriched environments with toys and climbing spaces show less stress and shed less fur.
Identify and minimize stressors like loud noises or new pets.
Use calming aids if needed.
Offer vertical spaces and cozy hideaways.
Hydration
Cats need enough water to keep their skin and coat healthy. Place water bowls in safe, quiet spots and change the location sometimes. Wet food adds extra moisture. A 10-pound cat should drink about one cup of water daily. Good hydration helps prevent excessive cat shedding.
Good hydration keeps your cat’s skin and fur in top condition. If your cat is dehydrated, their coat may lose its shine.
Vet Consultation
If you notice bald spots, skin irritation, or your cat shedding a lot more than usual, it’s time to see a vet. Your vet may do a physical exam, skin scrapes, or blood work to find the cause. Treating the problem early helps restore your cat’s healthy coat and stops excessive cat shedding.
