At Innovet, we treat a cat's coat as a window into their health. A glossy, even coat usually means things are going well underneath. A dull, greasy or thinning coat, or a sudden change in how much your cat sheds, is often the first sign that something is worth a closer look. Cats are famously good at hiding when they feel off, so the coat can speak before they do.
This guide covers why cats shed, what a healthy coat actually needs, the role nutrition and omega-3 play, and the signs that mean it is time to call your vet rather than reach for a supplement.
Why cats shed, and what is normal
Shedding is normal. Cats constantly cycle hair, growing new strands and dropping old ones, and most will shed a little all year with heavier periods as daylight and temperature shift through the seasons. In Australian homes with heating and cooling, that seasonal rhythm can be blurred, so steady year-round shedding is common and usually nothing to worry about.
What matters is change. A cat that suddenly sheds far more than usual, develops bald patches, or whose coat becomes matted, flaky or greasy is telling you something. The same goes for over-grooming, where a cat licks one area bare, which can point to itch, pain, allergies or stress rather than a coat problem on its own.
What a healthy cat coat needs
A good coat is built from the inside out. A few things do most of the work.
- Quality protein. Hair is mostly protein, and cats are obligate carnivores with high protein needs. A complete, meat-rich diet is the foundation of a healthy coat.
- Essential fatty acids. Omega-3 and omega-6 fats support the skin barrier and the natural oils that give a coat its shine. These are a common weak point in everyday diets.
- Hydration. Cats are notoriously poor drinkers. Dry skin often traces back to low water intake, so wet food and fresh water both help.
- Regular grooming. Brushing removes loose hair before it is swallowed, spreads natural oils, and lets you spot lumps, scabs or parasites early.
The role of omega-3 in skin and coat health
Of all the nutrients tied to coat condition, omega-3 fatty acids get the most attention, and for good reason. They support the skin barrier that keeps moisture in and irritants out, and they are involved in calming the kind of low-grade inflammation that can leave skin itchy and a coat dull. Marine sources such as fish oil are especially useful because they supply the long-chain forms of omega-3 that cats use most readily.
Everyday cat diets are often heavier in omega-6 than omega-3, so topping up omega-3 through diet or a targeted treat is a sensible, low-effort way to support skin and coat. We frame this as nutritional support rather than a cure. Omega-3 helps a healthy cat look and feel their best, but it is not a treatment for a diagnosed skin disease, which is a job for your vet.
Grooming and home care for cats
Even self-cleaning cats benefit from a hand. Short-haired cats are usually happy with a weekly brush, while long-haired cats often need a few minutes every day or two to stay free of mats. Regular brushing also reduces the amount of hair your cat swallows, which can mean fewer hairballs.
Keep an eye on the skin while you groom. Redness, scabs, flakes, black specks that could be flea dirt, or any sore your cat keeps returning to are all worth noting. Year-round parasite prevention matters in most of Australia, since fleas are a leading cause of itchy skin and over-grooming in cats.
When to see your vet
Nutrition and grooming support a healthy coat, but they are not the answer to every skin problem. Please book a vet visit if your cat has bald patches, open or weeping sores, persistent scratching or over-grooming, a sudden change in coat quality, or any lumps under the skin. These can signal allergies, parasites, infection, pain or an underlying medical condition, and they need a proper diagnosis rather than a supplement.
Where GlowBites+ fits
We made GlowBites+ as a skin and coat treat for both cats and dogs, built around the nutrients that support healthy skin and a glossy coat, and made in Australia to human-grade standards. For cats, it is an easy, low-fuss way to support coat condition day to day, given as a small reward rather than a chore. Because it suits dogs too, it is handy in multi-pet homes.
Think of GlowBites+ as everyday nutritional support for a cat that is already well, alongside good food, fresh water and regular grooming. If your cat has a skin problem you can see or that is bothering them, start with your vet.
Frequently Asked Questions
What supplements help a cat's coat?
Omega-3 fatty acids, especially from marine sources, are the most widely used for skin and coat support, alongside adequate quality protein. A skin and coat treat or supplement can help top up these nutrients. They support a healthy coat rather than treat a skin disease, so see your vet if there is an actual skin problem.
Why is my cat shedding so much?
Some shedding is normal and varies with the seasons. Heavier shedding can be linked to diet, stress, indoor climate, parasites or an underlying health issue. If shedding is sudden, comes with bald patches or skin changes, or your cat is over-grooming, see your vet.
Can diet really change my cat's coat?
Yes. Because hair is mostly protein and the skin barrier depends on essential fats, a complete diet with enough quality protein and a sensible omega balance is the foundation of a healthy coat. Hydration helps too, which matters for cats that drink little.
How often should I brush my cat?
Short-haired cats usually do well with a weekly brush, while long-haired cats often need brushing every day or two to prevent mats. Regular grooming also reduces swallowed hair and the hairballs that can follow.
When should a dull coat worry me?
A gradual seasonal change is usually fine. A dull, greasy or thinning coat that appears suddenly, or comes with itching, sores, bald spots or changes in appetite or behaviour, is worth a vet visit to rule out an underlying cause.
