From what fish is the fish oil in this product derived from?

Answer by Chewy • Nov 14, 2025
The fish oil in this supplement is made from anchovies, sardines, mackerel, and herring.

My fish oil is being delivered today and it's only going to be about 10° outside. Will it hurt it if it's frozen until I get home?

is it unflavored

First and foremost (and most importantly), my cat's coat has improved quite a bit which was why I bought this oil. She had dry skin and lots of dandruff, and since taking this for over a month now, I've already seen improvements. I wasn't worried about my cat being picky with the oil because she will eat just about anything, so thankfully I didnt have to worry about that. That being said, it was odorless. The dropper itself isnt connected to the cap as mentioned by others so I have to keep it separate from the actual oil, and that's a bit of an inconvenience.

My cat has previously had an almost dusty looking coat, but she’s been taking this oil for around a year now and I can see a complete transformation when I look at older photos. I’m sure this has other health benefits, but her shiny coat is what I notice most!

The dropper it comes with is kind of cheaply made but most of all my cats didn’t not like it. Normally they always eat every bit of their wet food but when I added this, they left a good amount of the wet food uneaten. Would not recommend if your cat is picky.

Heavy packaging!

I'm not writing about Omega-3. I'm writing about how your company has sent another box which is IMPOSSIBLE for me to pick up. I don't know how any person could have picked it up. I am disabled and have requested two times for you to put multiple items in more than 1 box. I had to leave the box out in the cold/rain until I could open it and bring in one item at a time! MORE importantly, many of the cat food cans were dented in, and a container of the cat litter BROKE OPEN and went all over the inside of the box. I scooped up as I could, but it left me with less than half of a container - which I will not get reimbursed for. PLEASE break up the orders into smaller boxes that are lighter! If I have to make my order smaller in order to get smaller boxes, it costs me too much in shipping, so I try to order one shipment at a time. PLEASE do not send another ENORMOUS box or I will have to find an alternative place to shop. Thank you.

Finicky senior cat with several medical issues. Her vet suggested that omega-3 might slow down her cognitive decline. This product does not have that super fishy smell, dosing was made easy and she likes it mixed into a broth. She also seems more agile so her joints have benefited also.

My 16 year old cat really likes this added to her food! I wish the dropper was part of a screw on cap for cleaner storage and use. There is no strong odor, which is something I was concerned about.

My cats live in the northeast. Every year during the winter months, they get terrible dandruff from the dry air. I put the drops on their wet food twice a day. After one week of using this product, the dandruff started going away. I also comb them regularly to remove loose hair and dandruff. Their fur looks and feels so much healthier.

I'm sure this is a good product, but unfortunately I cannot get my cat to eat even the smallest dose of this fish oil. I've hidden it in treats and his food, and despite it not smelling much at all, he somehow knows it's there and won't touch it.

Cat won't eat food after this is on it

Fuzz has very flaky skin, no fleas, so my vet suggested this product. I've tried, and she just won't eat the food once this is on it. I asked my vet to prescribe

Fuzz has very flaky skin, no fleas, so my vet suggested this product. I've tried, and she just won't eat the food once this is on it. I asked my vet to prescribe a food for her, because she's old (don't know her age, abandoned we brought indoors a few years ago) but for us, this was a waste.
