Best Overall
Ensuring your dog or cat is getting sufficient nutrients from their diet is important in raising a healthy and happy pet. Your pet may not properly absorb the fatty acids or may have allergies to certain foods that prevent them from getting proper nourishment.
A great way to ensure your cat or dog has a well balanced and complete diet is to add necessary supplements to their diet.
Oils are often used to supplement or add fatty acids to a pet’s diet as they offer a lot of benefits. It’s one of the easiest ways to add nutrients to your cat or dog’s diet as oils are somewhat discrete in food.
We have created the ultimate list of oils to use in your dog or cat’s diet. However, we recommend you consult your veterinarian before adding or taking away anything from your pet’s diet. Giving your dog the wrong dosage or supplement can lead to digestive issues and long term intestinal damage.
Please note that the dosages we recommend may not be accurate for your cat or dog, as there are many things to consider. Your pet’s weight, health, and age all factor in the dose of oil you should be adding to their diet. Always read the label on the back on the supplement and speak with your veterinarian for more information.
Now, let’s get into the eight oils most recommended for cats and dogs and their benefits!
Hemp Oil
Hemp oil is rich in antioxidants, vitamins, minerals, and omega-6 and omega-3 fatty acids. It promotes a healthy metabolism, weight, and can help with certain infections and the immune system.
Not only does hemp oil offer impressive benefits for your pet’s health, but it also provides pain and anxiety relief due to better-balanced metabolism. If your cat or dog struggles with joint or muscle pain, hemp is a great natural remedy.
Furthermore, hemp oil is helpful in calming your pet’s nerves, it comes in handy for cats and dogs that have separation anxiety or stress in general. If your cat or dog tends to get agitated and chew your furniture while you are gone, hemp oil will calm their nerves and help them feel comfortable alone. In other words, you won’t need to worry about coming home to a stressed dog or destroyed couch!
Furthermore, hemp oil promotes a healthy coat and moisturized skin. It is a great oil to use in your pet’s diet. With a healthy coat and skin, your pet won’t need to be bathed as often as dirt will fall off smoothly.
We recommend:
- If you are looking for a product containing hemp oil for your cat, we recommend our Hairball relief paste. Which also relieves constipation, dry cough and occasional vomiting associated with hairballs. Made with 100% natural and safe ingredients.
- Our most popular product here at Crocx is the Hemp oil nutritional supplement with 500 positives reviews on Amazon. All natural, made with 100% pure hemp oil (90 000 mg). This supplement is suited for pain relief and general healthy metabolism, but is well known for reducing dog’s hair loss in less than 12 days.
Fish Oil
Fish oil is packed with two essential fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These two fatty acids help with inflammation due to allergies, itching, dandruff, and hot spots.
Natural triglyceride oil is the most common and the easiest for the body to absorb. Fats sourced from salmon, herring, sardines, albacore tuna, and other fish higher classified in the food chain offer the most omega-3 fatty acids.
You can find fish oil in pump bottles or capsules, but make sure to store them in your refrigerator for the best longevity! Fish oil that has gone bad may not be as effective or may cause digestive issues.
The average dose of fish oil for a dog is 1,000 mg for every 30 pounds of body weight. However, you also need to take your dog’s diet into account as some foods are already rich in EPA and DHA. Too much fish oil can lead to an upset stomach or may cause blood thinning.
You can give your cat about 30 mg per pound; however, the dosage for a cat is a bit more touchy. A veterinarian’s recommendation will go a long way in finding the right dose for your cat.
Cod Liver Oil
Cod liver oil contains fewer levels of omega-6 and omega-3 fatty acids than oils from fish higher up the food chain such as salmon. However, it does contain high amounts of vitamins A and D.
These vitamins need fat to be adequately absorbed. Thus, it is best to add oil to your pet’s food. Cod liver is best for animals that don’t need a large amount of fatty-acids added to their diet.
Flaxseed Oil

Flaxseed oil is an excellent supplement for dogs and cats with allergies. It helps with mobility in arthritic pets, inflammation, blood pressure, allergy relief, and kidney function. It also offers fibret promote a healthy digestive system.
Ground flaxseed is the best and safest form for your pet because full flaxseed does not absorb properly. It is recommended to give a small dog (under 30 pounds) about ½ teaspoon of oil or ground flaxseed daily, one teaspoon for medium dogs, two teaspoons for large dogs, and one full tablespoon for very large dogs.
You can give your cat about half a teaspoon or about 20% of their calorie intake, depending on their weight.
It is recommended to start with a smaller dosage and build from there, depending on your cat or dog’s weight. To ensure your pet doesn’t get any digestion issues from the flaxseed oil, divide the dose between day and night.
Krill Oil
Unlike most fish oils that come from higher up the food chain, krill oil is sourced from small shrimp-like organisms. Your pet is less likely to be contaminated with mercury as smaller fish have less mercury in their system. However, it is not typically recommended for pets as it may create an imbalanced amount of vitamins compared to fatty acids.
You can speak with your veterinarian for more information about krill oil and if it is right for your cat or dog.
Coconut Oil
Not only will it make your dog’s breath smell better, but coconut oil is mainly known for maintaining proper digestion and a healthy coat. It also helps with inflammatory bowel disease and poor bowel absorption. Some pets, such as Bulldogs, are prone to digestive problems and can benefit from an oil supplement like coconut oil as it will help with the absorption of the nutrients in their food.
Coconut oil has high levels of Medium Chain Triglycerides (MCTs), which help with brain health and energy. It also doesn’t have high levels of omega-6 and omega-3 fatty acids. Thus, coconut oil is a safe choice to add to your cat or dog’s diet as It will not interfere with the level of fatty acids in their food.
Coconut oil is also quickly metabolized and boasts more than 90% of healthy saturated fats with smaller amounts of unsaturated fatty acids. It is a healthy alternative to add healthy fats to your pet’s diet if they deal with weight or health issues.
Opt for organic virgin cold-pressed coconut oil, available in most grocery stores, as this is the purest form. For your dog, a fourth of a teaspoon for every 10 pounds, twice daily, is a rule of thumb. However, keep in mind that coconut oil adds more calories (40 for every tsp). If your dog is not very active, it may be best to opt for a different oil.
For an average-sized cat, start with about ⅛ of a teaspoon until you eventually reach up to ¼ or ½ of a teaspoon. Keep in mind; cats are not as active as most dogs so make sure the extra calorie intake works with your cat’s lifestyle.
Olive Oil
Olive oil is rich in antioxidant capability due to the polyphenols, vitamin E, chlorophyll, and carotenoids. It helps improve the immune system and is effective in lessening the symptoms of cardiovascular disease and diabetes.
Olive oil does not contain an impressive amount of omega-3 and omega-6 fatty acids. It is not the best option for increasing your cat dog’s intake of fatty acids, but it does help improve their calorie intake. There are about 40 calories per teaspoon. This is beneficial for cats and dogs that are active or have weight problems.
Furthermore, olive oil is good for pets that struggle to tolerate omega-3 and omega-6 fatty acids due to gastronomical intestine issues. It is also great for younger pets that can’t easily digest the high amounts of fatty acids in other oils.
Look for 100% olive oil, nothing mixed, as this is the purest form. You can add half of a teaspoon to the food of a small dog under 20 pounds, a full teaspoon for dogs weighing 30 to 40 pounds, and up to a tablespoon of olive oil to dogs of 50 pounds or more.
Moreover, it is recommended to give a small cat three tablespoons of olive oil a week. A medium-sized cat can have up to half a tablespoon a day. A large cat can have up to half a spoonful a day. As with most oils, start small and build-up to the full amount to observe how your cat is adapting to the new addition in their diet.
Sunflower Oil
Sunflower oil is commonly used to keep skin moisturized as many dogs and cats cannot properly synthesize linoleic acid (LA), a dietary source or supplement is necessary to maintain a healthy coat and skin.
Sunflower oil also promotes energy, healthy immune function, heart health, and normal organ function.
This superfood oil is already found in a lot of pet food and treats as it contains the necessary amount of omega-6 fatty acids needed for your pet’s diet. It also contains lower saturated fat compared to animal fat.
Though sunflower oil has sufficient levels of fatty acids, it doesn’t have enough levels of arachidonic acid (AA and ARA), an omega-6 fatty acid only found in animal fats. Thus, sunflower oil should not be used as a stand-alone source of fatty acids.
It is recommended to use sunflower oil with a home-cooked diet. A medium dog can take up to one teaspoon daily; this offers about five to eight grams of omega 6. However, keep in mind that all fats are calorie-dense, with one teaspoon of sunflower oil coming to about 40 calories. Also, take into account omega-3 supplementation as sunflower oil doesn’t provide a sufficient amount.
In regards to finding the right dose for your cat, we recommend asking your veterinarian as they will be able to measure better the correct amount based on your cat’s age, weight, and health.

You do not want to give cod liver oil to animals. There is too much vitamin A and D which can become toxic. It also depletes the kidneys of protein and is hard on the liver when vitamin A levels rise to high. There are also arsenolipids or polar arsenic compounds that have been found and isolated from cod liver oil. I don’t think you guys are qualified to give any pet owners advice your information is way off. Please verify your statements
Hi I have a 6 month old kitten. He only prefers the tiki cat wet food, but most of their stuff is pretty low in fat percentage. Would adding one of these oils be a good idea to up the fat percentage in his food just a little bit?
Adding some fat with these oils is a great idea.
Tiki depending on what flavor/type has plenty of fats in it already especially looking at dry matter basis. It’s not a bad food compared to most. If you really want the best for your pet don’t give them lab made hazardous minerals. The problem with it and 99% of all pet foods is tricalcium phosphate, sulfates, sulfites sodium selenite and selenate etc that are lab made and disguised as healthy vitamins or minerals. They are not healthy. Natural sources of vit and minerals your pets body can regulate adsorption partially, these lab made phosphorus sodiums are completely absorbed and build up to levels causing many health issues. Ever wonder why so many cats have kidney problems? Phosphates. It’s in basically every store bought animal food. Read about these ingredients on nj.gov website hazardous substances and you’ll see how bad they are.
One of my cats has a problem with excessive and prolonged vomiting after he has coughed up a hairball. A vet recommended adding fish oil to his diet. Since he mostly eats dry food, and is a very picky eater, I have tried adding a small amount of fish oil (or more recently, salmon oil) to a tablespoon or more of canned food, as he won’t eat a lot of food in one sitting. He won’t always eat the food with the fish oil added, and especially now with the salmon oil, he won’t eat it at all. Is there a different oil that I could try to help with his problem?
Hi,
In regard of the description of the situation, we advise you to use the Hairball relief paste and the Crocx Pro Hemp Oil Nutritional Supplement on a daily basis.The premium cold-pressed hemp oil contained may help prevent hair loss. Less hair loss will reduce the risk of having other hairball events reoccur.
That being said, the Hairball relief paste Crocx is the best product that can help to fix this issue: http://crocx.co/en/boutique/pro-series-hairball-relief-hemp-paste/ ; http://crocx.co/en/boutique/nutritional-supplement/.
My cat needs a bit of oil in her diet to give her more energy and help her put on weight after an illness. Can you suggest which of these oils would be better for that. Also, what about peanut oil? Is that OK for cats? Or if you can suggest a website I can look at that would be great, too. Thanks.
My cat appears to have Feline Endocrine Alopecia..and excessive grooming. She is 2 1/2. Is there some type of oil I can put on her bald spots, or something. My concern is I do not want her licking anything that would be toxic to her.
Cold pressed hemp oil will most likely help in this situation but we advise you to check with a veterinarian first to ensure there is no ambiguity in using the Crocx Pro CHemp Oil Nutritional Supplement in that case.
Is grape seed oil okey for cats?
First of all, we are not veterinarians. That being said, the extract and organic grape oil is non-toxic to dogs and cats. Indeed, organic grape oil seed offers a certain amount of omega 6 if extracted from biological grapes.
However, the fruit is highly toxic to cats and dogs. The skin and flesh of the grapes contains substances that can cause kidney failure and can be fatal.
If you are looking for an oil rich in omega fatty acids, we recommend the Crocx Pro Hemp Oil Nutritional Supplement instead. Its balanced intake of omega 3,6 and 9 makes it an excellent food supplement for cats and dogs:

My 16 year old cat has been diagnosed with stage one renal disease and omega 3 has been recommended 295 mg EPA and 180 DHA…I use hemp for my health and am wondering if this is a good choice for my cat?
My cat is 14yrs old and we started putting oil in her food to help with skin and bowel problem now she will only eat her wet food if she has oil in is this ok
You should consult with a vet to be sure. Oils are great for cats, but I would make sure that she does not eat more than the recommended dose.
What about camelina oil? My house had a flea infestation which seems to be gone now but one of my cats, 8 year old tabby male, developed excessive grooming. The vet said due to flea allergies but fleas are gone and he won’t stop! Missing fur and getting raw spots and sores from so mush grooming!
Yes camelina oil is also a great choice, very similar to hemp oil. The benefit of hemp oil over camelina is that hemp oil also contains GLA (gamma linolenic acid) a type of Omega 6.
Can i use canola oil to my dog?
First of all, we are not veterinarians. That being said, the ideal is to use cold pressed organic canola oil, this way we make sure that it does not have hexane or pesticides. Indeed, a certificate of analysis from an independent laboratory is requested in regard of the level of erucic acid.
Hemp seed oil is in my opinion a better choice. Since then, hemp seed oil has contained gamma-linolenic acid, which is very rare in nature.
I have a 8 yr old diabetic cat who is 17 lbs.
His stools are about every 2-4 days and almost always dry balls. What is the best oil to put in his food and how often.
You should consult with a vet to be sure.
Can I use more than one at a time
Yes you can !
Great info. Have allergy dog can I use more than one? Also he only eats fish food is that ok to add fish oil to
You can use more than one and yes you can combine with fish oil
My cat has dandruff !!!! What is the best oil to help with this?
Hemp seed oil or coconut oil is great for dandruff, you could also use our shampoo
I use virgin olive oil
A small amount (half a tsp) of coconut oil mixed into her wet food. Cats should be having either only wet food or both wet and dry, in small portions. Since they would naturally get water from blood of their kill in the wild, domesticated cats don’t like drinking from still water either from this carnal instinct. The oil/wet food keeps a hydrated healthy skin & coat. Coconut oil can also be applied topically for them, same amount.
I just wanted to back up the above. I treated my poor kitty like a dog, expecting her to drink water and eat dry food (wet food *can* cause dental problems in dogs if they don’t chew things to clean their teeth/gums) but with cats wet food is absolutely necessary. Dehydration for cats is easy to get and can quickly lead to organ failure. Wet food is absolutely required for cats’ hydrative needs.
Hemp oil with be the best. If you buy the Crocx Hemp oil supplement, all the dosing is on the label.
Hey um my cat is not eating and even if she she eats she throws up what oil will be the the best for her?olive oil??.
Hi my 10 year old cat has itchy skin intermittent despite being de flead and De wormed regularly which is best oil for her and how much ? She’s eating well and drinking thank you
I’d recommend vegetable oil, just a bit at first, wouldn’t go more than a teaspoon a day mixed in with their food.
