Dull coat, dry skin, visible dandruff, fur coming out in clumps: is the cat unwell or is it just a matter of diet? Let's look at the most common causes.
Dietary causes (the most common)
Essential fatty acid deficiency
Omega-3 and omega-6 are essential for skin and coat. Low-quality foods have little of them.
Solution: fish oil supplement (50-100 mg EPA+DHA per kg of body weight per day).
Too "dry" food
Only kibble for years → dehydration → dry skin → dandruff.
Solution: predominantly wet food.
Food allergy
Manifests on the skin, as well as in the intestines.
Solution: elimination diet with a veterinarian.
Non-dietary causes
Insufficient brushing
Especially in long-haired cats. Dead hair accumulates underneath, irritating the skin.
Solution: more frequent brushing (2-3 times a week or daily for long hair).
Dehydration
A cat that drinks little has chronically dry skin.
Solution: strategies to increase water intake (see dedicated article).
Advanced age
Senior cats have more difficulty grooming themselves and have drier coats.
Solution: assistance with brushing, targeted supplementation.
Stress
New animals at home, moving, conflicts: the cat grooms less (or too much).
Diseases
- Hyperthyroidism: dull coat, excessive shedding
- Diabetes: dry and fragile fur
- Kidney failure: dull, dry fur
- Parasites (mites, fleas, dermatophytes): localized dandruff, itching
When to go to the vet
- Sudden dandruff
- Fur coming out in clumps (alopecia)
- Intense itching
- Crusts, wounds
- Change in coat color
Exams: trichogram, skin examination, potential blood tests.
The ideal routine
- Regular brushing (frequency for the fur)
- Predominantly wet diet
- Omega-3 supplements
- Always fresh water
- Stable environment (stress reduction)
- Annual visits (blood tests after 7 years)
Let's sum it up
A dull coat is a thermometer of overall well-being. If the diet is correct and the environment is calm, the problem is often health-related. Never overlook prolonged changes in the coat: talk to your veterinarian.
