Will I get fishy burps?
Repeat burping or bad taste could mean your supplement may be oxidized. All Nordic Naturals fish oils are protected from exposure to oxygen at every step of production to help deliver an exceptionally fresh taste without fishy burps or aftertaste.
Are there options for me if I have a hard time swallowing pills?
Yes. We offer liquid options for many of our fish oil products, and our fish oil soft gels are chewable for those who have difficulty swallowing pills. Some products are also available in smaller, easier-to-swallow mini soft gels or chewable gummies.

10/10. Bye bye dandruff!
10/10. We moved to a new apartment and it is apparently a little too dry, my sweet Ivy had dandruff appear out of nowhere and I could tell she was a little more itchy than usual. We’ve been giving her this oil for a little over 3 weeks and it is already SO much better. Her coat is incredibly shiny and soft, she has stopped licking herself as much and she actually eats her food with the oil in it, she used to refuse other brands of omega 3 oil. I’ve been keeping the bottle in the fridge as suggested by someone else in the reviews and I love that it comes with its own dropper. Instructions are clear and the product really actually works. If you and your cat are struggling just like us, I recommend this product.

Extremely helpful!
My older cat (born in 2011, so 14ish) has notably better mobility with this added to her wet food. She can jump much higher and does more zoomies and active play, making her happier overall. This is a must for us, and I will continue to buy and use it for her as long as she lives!

Good Product But Bad Included Dropper
Love the product, just needs a better dropper. The one included was bent and janky. Always makes my hands get some on them and then they stink to high heaven like fish…hard to remove. Please upgrade your dropper or dispensing system.

Why didn’t I get this sooner??
We have a cat that is on medication that can be crushed and administered in her food. Everything was going fine for quite a while and then suddenly, she started to notice it and began to refuse to eat her soft food. If we didn’t put anything in it, she’d eat it. The minute I added her meds, she turned her nose up. I tried what I thought was everything yet nothing worked. I was ready to pull my hair out. My daughter mentioned that she ran into that issue once and used fish oil. I decided to give it a shot.It arrived quickly and was packaged well. The dropper leaves something to be desired, but it still works and I am able to clean it just fine. I prepared her food, crushed and stirred in her meds and then added the amount recommended but slowly doing drips all the way around the food trying to get it everywhere. I set it in front of her and watched her sniff it a few times. She took a lick, then another one. That was that. She ate it all! Best part, it’s been over a month and she’s still eating it all! She hasn’t had any digestive issues from it and it has helped with her coat, which does tend to look a little less shiny due to her condition. I couldn’t be happier! I will definitely be ordering this again.

Works FAST
I couldn’t be more impressed with the results from Nordic Naturals Omega-3 Cat! I started my cat on this fish oil just a few days ago, and the difference has been incredible. His coat is noticeably shinier, and the persistent dandruff he had for months vanished within two days of starting this supplement. I was honestly surprised at how fast it worked!I love that it’s unflavored, making it easy to mix into his food without any fuss—he doesn’t even seem to notice it’s there. (He’s very fussy) The dosage is straightforward, and I appreciate that it’s non-GMO and made with high-quality ingredients. Knowing that it also supports heart and immune health is just an added bonus.If you’re looking to improve your cat’s coat, skin health, and overall well-being, I highly recommend giving Nordic Naturals Omega-3 a try. It’s definitely a game-changer!

Good oil, bad packaging with cheap plastic dropper
The oil is good quality, but I knocked off 2 stars for the senseless packaging. This stuff is VERY stinky, and to have it in a screw-cap bottle with a separate cheap PLASTIC dropper is a terrible choice. The cap is prone to leaks and drips, so I’ve nearly dropped and shattered a slippery bottle more than once. You literally have to give the plastic dropper a hot, soapy bath after each use unless you want to smell fish oil all the time wherever you store it. I was putting it in a sealed plastic bag in a drawer to keep the stench at bay, but finally caved and bought glass medicine bottles with dropper caps and transferred this oil into one of those. Nordic Naturals needs to rethink this bottle – it should come with a screw-in glass dropper top. That said, my cats’ skin is no longer dry and itchy, and their coats are now super soft.

The dropper is not incorporated to the cap
READ: The dropper is not incorporated to the cap!!! I love this product. I bought it a while ago and it really improved my cat’s fur so I know it is effective. I just add it to her wet food and she doesn’t have an issue with it. Now She has some dandruff and I got it again because I know it’s good… however the new design is terrible. The dropper is not incorporated to the cap so it’s messy and Not easy to use. You’ll have to rinse it every time otherwise it’ll get sticky and contaminate the bottle. I will have to buy another brand next time because the inconvenience of this design is not worth it.

Nordic Naturals Cat Omega-3ein wirklich hervorragendes Öl – riecht frisch und angenehm, ganz ohne den typischen Fischgeruch. Ich finde es sehr gut, dass es in verschiedenen Größen erhältlich ist. Da das Produkt recht teuer ist, kann man zuerst die kleine 60 ml-Flasche ausprobieren und später die größere nehmen.Das Omega-3 ist für Katzen sehr wichtig – unterstützt das Nervensystem, wirkt entzündungshemmend und verbessert das allgemeine Wohlbefinden meiner Katze deutlich.Ein kleiner Nachteil: Die Pipette ist separat vom Deckel, und man muss sie jedes Mal extra reinigen – das ist etwas umständlich.Trotzdem ein qualitativ hochwertiges Produkt, das ich auf jeden Fall weiterempfehlen kann. 🐾

Sehr gutes Öl. Katzen fressen es problemlos mit.
