It’s easy to spot cat dandruff. It shows up as white or gray flakes on their fur. Usually caused by dry skin, it can make your cat feel itchy. Although most of the time, feline dandruff is a minor inconvenience and can be treated at home, in some cases, it can stem from serious underlying conditions. If your cat has excessive dandruff or other symptoms, it’s best to get it checked out by your veterinarian to find out how best to treat your cat’s dandruff.

Some of the causes of cat dandruff include obesity, allergies, fleas, mites, malnutrition, or dry air. As long as your cat is otherwise healthy, most cases of cat dandruff are easily treated. Read on for seven ways to treat cat dandruff and keep your feline’s coat looking fresh.

Brushing your cat’s fur is the first step to keeping their coat shiny and fresh. Not only is it a bonding experience to share with your cat, but brushing your cat’s fur distributes the animal’s natural oils and removes dandruff. Brushing also removes dead skin cells, dust, loose hair, and can improve circulation. Cats with long fur may even need more than one brushing per day.

2: Use a Humidifier

This can help prevent dry, flaky skin for you and your pets. You can buy a humidifier or try this DIY method for making your own.

Feeding your cat a healthy diet that gives him the nutrients he needs is important for your pet’s health. Overweight or obese cats can struggle to groom themselves, which can cause flaky dandruff to build up. Also, feeding your cat a diet that includes Omega-3 and Omega-6 essential fatty acids has been found to improve skin health. Some foods are supplemented with fatty acids. You can also buy over-the-counter fish oil supplements to feed your cat. Food allergies can also cause skin issues in pets. You may need to investigate what is in your pet’s food and eliminate anything that may be causing skin irritation or other allergies.
