For cats that dislike soft chews and capsules, this liquid salmon oil should do the trick. Made of quality wild-caught Alaskan salmon, the supplement comes in a pump bottle for easy administration. Pump according to the recommended dosage of fish oil based on your cat’s weight.

As liquid fish oil is prone to oxidation and turning rancid, it is recommended to keep the product refrigerated after opening. Zesty Paws made a tasty product that cats love. However, it comes with a strong fish odor that can linger in your cat‘s mouth.

Give your feline buddy a balance of essential fatty acids with this product. It combines Omega 3, 6, and 9 from flaxseed, borage seed, and fish oil. So far, there are not much complaints when it comes to the scent and taste of the product. Most customers fuss about the size of the supplement as it comes in a large, over-an-inch size capsule.

It is best to avoid giving this to kittens. The large capsule also contains a bigger dose. Unless you have multiple cats to give fish oil supplement, you will be wasting a lot of product. The administration could either be by swallowing the capsule or by adding a few drops on their food.

As to the benefits, this vet-approved pet supplement is good for your pets’ skin, joints, and heart health. Most of the satisfied customers used the product to resolve their pets’ dry skin, thinning hair, bald spots, and itchy flakes.

Compared to other fish oils, Omegease is free of stinky fish odors. It derives its Omega-rich fatty acids from anchovies, herring, and sardines caught in the wild. They use non-predatory fish to ensure there are no contaminants, mercury, and other toxic chemicals.

Omega 3 for Cats – Guide 

If you’ve heard about Omega 3 fatty acid supplements for cats and you are considering giving them to your feline buddy once in a while, you should read the guide that we have prepared for you below.

Why go for cat Omega 3 oil?

Healthy fatty acids such as Omega 3 and Omega 6 have plenty of anti-inflammatory effects and they can be beneficial for a broad array of medical conditions from chronic kidney disease to arthritis, skin issues, as well as allergies. But as is the case with everything else in life, you can get a bit too much of a good thing. We will discuss that later on. Let’s see what sources of Omega 3 there are out there.

Nuts, flaxseed, and vegetable oils

Most nuts and seeds contain Omega 6, not Omega 3, but there are some that have a good amount of the latter, too. Flaxseeds are just an example.

What’s important to note here, however, is that dogs and cats aren’t capable of ‘processing’ the entire Omega 3 they might get from these sources, so they only get about 1-2% of what they’re supposed to. Omega 3 must convert into DHA and EPA, and plant-based sources can only be converted into EPA, anyway, and only in a small amount. By the way, vegetable oils – from sunflower oil to coconut oil – contain no Omega fatty acids at all.

Squid oil, fish oil, and krill oil

Squid oil contains nine fatty acids, and DHA tops the list. However, EPA comes in only fourth. Squid oil isn’t the best of choices because it also contains a high quantity of cholesterol, which, as we all know, is linked to the development of various medical conditions.

Fish oil, along with cod liver oil, are two of the most popular and common sources of DHA and EPA. While it is true that this option is probably the best because it is the only bioavailable source and one that contains enough of both fatty acids, there can be some issues connected to this type of product.

One of them is the fact that some fish are farmed, they aren’t wild. Farmed salmon has been linked to exposure to all sorts of chemicals. Naturally, you do not want to give your pet a fish oil supplement that comes from such sources. To avoid any such issues, check out the International Fish Oil Standards Program, an independent group that tests oils extracted from fish.

Krill oil is a healthy non-fish alternative that contains Omega 3. It’s also quite healthy, provided that it is harvested from clean waters.

Algae oil is another option you have at your disposal, but we’d like to note that it is mostly recommended for vegans (humans), not for cat, because it also contains Omega-6 fatty acids which could be problematic. Some algae have been genetically modified to produce more EPA, so there’s that controversy to take into account, as well.


Despite the Internet being filled with dozens (if not hundreds) of videos that can explain how you can give a cat a pill, the truth is that many cat parents will shy away from it and won’t want to upset their feline friend. I have personally gone through horrible such experiences in the past, and the truth is that I love my cat so much that I turn to mush and can hardly use any vet skills I might have acquired during my 7 years of practice if I notice that she’s experiencing any discomfort.

When it comes to omega 3 fatty acids for cats, you have three major options – capsules, liquid, or chewy tablets. Not all cats like the taste of the chewy tablets, so they might not want to take them on their own.

Capsules are the most difficult form to administer, and that’s because they’re usually on the bigger side of things. Oils and liquids are to be preferred, in my opinion, and that’s because they can be added to wet food or administered directly.

Side effects

As we said in the beginning, there is something like too much of a good thing, and overzealous and over-caring pet parents might feel the need to pour a gallon of fish oil onto their pet’s food, but that is definitely not recommended. Every formula comes with clear instructions and dosages, so you should always respect them.

Fish oil can cause some serious side effects when it is overdosed and these range from gastrointestinal symptoms and changes in the immune system to weight gain and an alteration of drug metabolism.

The recommended dosage of omega 3 for cats is 2.5mg EPA+DHA per metabolic body weight. For dogs, it’s 30mg EPA+DHA per metabolic body weight.

Frequently asked questions about Omega 3 for cats

Can I give my cat omega 3 fish oil?

There’s no easy way of providing an answer to this question, and that’s because every cat is different. If your cat has perfect health but you’ve noticed that her coat isn’t as shiny or soft as it used to be, sure, you can supplement with a bit of Omega 3.

However, always make sure that you respect the right dosage, and if it’s not been recommended by a vet, I would actually suggest using half of the typical dosage. It’s practically impossible to administer an overdose if you give half of the dose to a healthy cat.

Do cats need Omega 3?

Not necessarily, but it isn’t a bad idea to give it to them, anyway. Omega 3 can offer plenty of benefits, but if your cat is perfectly fine and eats only the right things, you might find that it makes no sense to add the supplement to her diet. I would recommend trying to switch to a raw diet instead of one based on commercial cat food and you’ll see the difference. If your cat likes it, perhaps it’s not a bad idea to feed her some salmon once in a while since it’s rich in Omega fatty acids.

How much Omega 3 does a cat need?

The recommended dosage of omega 3 for cats is 2.5mg EPA+DHA per metabolic body weight. For dogs, it’s 30mg EPA+DHA per metabolic body weight.

Can I give my cat human Omega 3?

If it contains the right things and you always make sure that you never exceed the dose, you can. However, I would suggest calling your veterinarian before you give any type of supplement at all, especially considering that he or she is the person that’s aware of your cat’s medical history and can recommend you the right products in accordance with your pet’s health status.

Can you give a cat with pancreatitis Omega 3?

Pets with sensitive digestion can experience a series of issues when you increase their dietary fat. Any cat with a history of pancreatitis or gastrointestinal problems should be weaned onto fatty acid supplementation with care so that the fat levels are well tolerated.

Cats that are particularly sensitive to dietary fat might show changes in the consistency of their stool, and some might even experience diarrhea. If you notice that this has happened, get in touch with your veterinarian as soon as you can and stop supplementing your cat’s diet with any oil that contains Omega 3.

Does Omega 3 lower cat shedding?

It does lower the shedding, but it is not guaranteed to stop it, especially if the pet you’re administering the fatty acids is known to have a history of dermatological issues. It does help, that’s for sure, as attested by many people who have tried it and the results I have noticed in the past, too.

What cat food is high in Omega 3?

If you are expecting an answer in the lines of ‘this brand’, I’m going to be completely honest and say that I do not trust any brand of cat food currently available. Sure, I feed Royal Canin to my cat, too, especially when I’m extremely busy, and I usually make sure to select the varieties that contain as little artificial preservatives and colors as possible. However, the only way of making sure that your cat benefits from healthy nutrients is to feed her a raw diet.

If you haven’t gotten your kitten accustomed to the taste and consistency of commercial dry food, I would suggest starting her on a raw diet now. Pets can become addicted to certain food brands as such companies might use taste enhancers or oils (not necessarily the good ones) in the manufacturing process. I’d say to feed your cat a raw diet and use fish oil to supplement the Omega 3 – that is, unless you’re feeding her real cod and wild caught salmon.

Omega fatty acids – Therapeutic sources and effects

Fat can contain fatty acids, but in varying amounts. Beef fat has a low percentage of fatty acids while fish oil or sunflower oil have significantly larger percentages. Marine oils are great sources of both EPA and DHA, but there are other plant sources, too, such as safflower oil and sunflower oil.


Fatty acids can help pets deal with certain medical conditions, or rather, the clinical symptom of diseases. For example, Omega 3 helps with allergies and autoimmune conditions, arthritis, as well as several other inflammatory diseases such as colitis, rheumatoid arthritis, and inflammatory bowel disease.

EPA is extremely helpful when it comes to slowing down the growth of certain yeast strains such as Malassezia spp. Omega 3 fatty acids can also prevent many cardiac issues, particularly in older pets. Last, but not least, one of the most important therapeutic effect that fatty acids have is that they can prevent cancer, at least to some extent.

Omega 3 fatty acids are essential when it comes to the healthy development of the retina and visual cortex, so they can do a bit of difference with regard to your pet’s eyesight, too. Of course, they won’t naturally reverse conditions such as cataracts, but they can prevent them.

What do fatty acids do for skin?

Brittle, dull, and dry hair coats usually respond to supplementation with fatty acids.

Cats can suffer from a medical condition known as miliary dermatitis (also known as ‘blotch’ or ‘feline eczema’) that can be caused by a wide array of factors such as bacterial, fungal, and parasitic infections to autoimmune diseases, hormonal abnormalities, as well as autoimmune disease. The disease is characterized by the presence of crusty, small-sized bumps spread on the cat’s skin, which can have redness underneath. In a nutshell, this skin condition can be significantly improved with fatty acids supplementation.

Fatty acids in conjunction with treatments

One thing that we would like to make clear is that fatty acids do not cure diseases. They do not have the ability to work like a magical charm, but they can do a lot of beneficial things if they are associated with medication. For example, a veterinarian might have to administer just half of the dose of glucocorticoids if the animal is suffering from an allergy and also receives omega 3 fatty acids during treatment.

Another aspect that needs to be considered is that omega 3 fatty acids don’t have an immediate effect. They usually take about a month to show any results, which means that pet parents have to have a lot of patience. Many dermatologic conditions in cats respond to fatty acid supplementation with success rate ranging from 40% to 65%.
