Giving your cat fish oil can help them thrive from head to tail! In addition to being a great supplement for overall health, cats’ coats especially benefit from the nutrients that fish oils, including cod liver oil, provide. But how does fish oil for cats work? Is cod liver oil the best choice for your cat? Where can you get the best fish oils for your cat? Let’s get into the details.
What is fish oil for cats?
Before diving into the specifics, it’s important to get a read on what exactly fish oil is — and how it works for cats.
Fish oils contain omega-3 fatty acids, a critical nutritional component for cats. They’re composed of almost ⅓ fatty acids, making fish oils a very effective way to supplement your cat’s diet. While cats who are eating a well-balanced diet are unlikely to need additional fatty acids, many cats can still benefit from fish oils.
Fish oils can be helpful in treating a wide variety of ailments in cats, from kidney disease to urinary tract problems and beyond. But fish oil is probably best known for supporting great skin and coat health in cats.
How do fish oils such as cod liver oil work to improve feline skin health?
Fish oil supplements improve cat skin health in a number of ways, including:
- Reducing inflammation. Fish oils, including cod liver oil, contain omega-3 fatty acids, which have anti-inflammatory properties. This can help to reduce inflammation and irritation in the skin that may be caused by a wide variety of factors, including allergies, fleas, and ringworm.
- Moisturizing the skin. Omega-3 fatty acids from fish oils also help to moisturize cats’ skin by keeping it hydrated. This can help to reduce excess dryness and flaking and make the skin look and feel healthier.
- Promoting hair growth. Omega-3 fatty acids also play a role in hair growth and development. This is because they help to support the production of collagen, which is a protein that is essential for healthy hair follicles.
- Strengthening the skin barrier. The skin barrier is the outermost layer of the skin that helps to protect against infection and environmental damage. Omega-3 fatty acids help to strengthen the skin barrier by increasing the production of ceramides, which are lipids that help to keep the skin barrier intact.
In addition to these benefits, fish oil supplements may also help to reduce shedding and improve the overall appearance of the cat’s coat.
It is important to note that fish oil supplements should not be used as a substitute for veterinary care. If your cat is experiencing skin problems, it is important to see a veterinarian to rule out any underlying medical conditions.
What’s the best fish oil supplement for my cat?
Small fish are a better source of omega-3s than large fish like cod because they are lower in the food chain. Omega-3 fatty acids are produced by algae, which are then eaten by small fish. As larger fish eat the smaller fish, they accumulate the omega-3 fatty acids in their bodies. However, as the fish get larger, they also tend to accumulate more toxins, such as mercury.
While large fish like cod can still be a good source of fish oil, they’re more risky to use than those containing oils extracted from smaller fish. In addition to the source of the fish oil, you should also check for these important things:
- Purity and quality: The product should be free of contaminants like heavy metals, PCBs, and other toxins that can be found in fish. Look for products that have been molecularly distilled or have a certificate of analysis indicating purity.
- Formulation: Fish oil supplements for cats come in various forms such as liquids, soft gels, or chewables. Choose a form that your cat is most likely to take.
- Packaging: Fish oil can turn rancid if it’s exposed to light, heat, or air. Look for products in dark bottles or opaque packaging and store them as directed to maintain their freshness.
