Why Is My Cat Shedding in Winter?

If your cat is suddenly shedding in winter, you’re not alone. Many cat owners think shedding only happens in warmer months, but winter shedding is completely normal — and it often has surprising causes.

Below are the 6 main reasons why your cat sheds during cold weather and what you can do to manage it.

Quick Summary Table

Reason	What It Means
Indoor heating	Dry air causes loose fur and skin dryness
Seasonal coat change	Cats still adjust coats even in winter
Stress or anxiety	Stress triggers excess shedding
Poor diet	Lack of nutrients affects coat health
Skin irritation	Allergies or dryness increase shedding
Medical issues	Thyroid or skin conditions may be involved

1. Indoor Heating Causes Dry Skin

Heaters run constantly in winter, making the indoor air dry. Dry air leads to flaky skin and loose fur, causing your cat to shed more than usual.

Keeping the air humid helps reduce this type of shedding.

2. Winter Coat Adjustment

Holiday changes, guests, noise, or routine shifts can make your cat stressed. Stress can cause excessive shedding, even in winter.

Reducing environmental stress usually improves the coat.

4. Poor Nutrition

If your cat’s diet lacks omega-3, protein, or vitamins, their coat becomes dull and sheds more.
Cats need high-quality nutrients to maintain healthy fur throughout the year.

5. Skin Irritation or Allergies

Winter can trigger skin sensitivity, especially with:

• Dry air
• New blankets
• Seasonal dust
• Artificial fabrics

These can all cause itching and extra shedding.

6. Underlying Medical Issues

Some medical conditions cause winter shedding, including:

• Hyperthyroidism
• Fungal infections
• Fleas or mites
• Dermatitis

If shedding is excessive, see a vet to rule out medical problems.
