What Fish Based Cat Food Is The Best?

​Cats love eating fish.  Like all things, too much of a good thing can have undesirable consequences and too much raw fish for cats can lead to a possible Thiamine (Vitamin B1) deficiency in cats.

However cats can still enjoy their fishy dinners because canned cat food ​has Thiamine added to correct this imbalance.  As cat food is specifically formulated for cats it also contains other vitamins and minerals for good health. Some cats require a diet that will take into account allergies or other dietary restrictions.

Canned cat food can be smelly and interestingly that remark often pops up in reviews.  Kitty does not mind the smell even if it can be a bit offensive​ to us mortals.

1.Fancy Feast Seafood Feast Variety Pack

Instinct Original Grain Free Real Salmon Recipe Natural Wet Canned Cat Food by Nature's Variety, 5.5 oz. Cans (Case of 12)

This is a brand well known to me as Fancy Feast seemed to steal my kitty’s heart at a young age. He was a loyal customer for many years, in fact until he passed away in 2018.  With Fancy Feast you know you are getting a product that is high quality and that quality has not changed ​over time.

As with any cat it can be a bit of trial and error to find the preferred exact fish flavors.

This pack has three different ​flavors, Seafood Feast in Gravy, Tuna Feast in Gravy and Salmon Feast in Gravy.​ ​This food itself is tender chunks with gravy. Is your cat a gravy lover? If so this is the cat seafood for you.  ​This was one box that made it into our shopping trolley on a regular basis.

Our cat often had a lick of the gravy as a little​ starter. He would even walk away and then return to tuck in. One reviewer added a little water to increase the amount of gravy. The fact that the food is in gravy means that the cat is also getting moisture with a meal which is a good thing.

​There are ​24 cans, ​8 of each flavor. If you are comparing retailer prices ensure that you are comparing like for like.

A normal serving would be ​​2 cans a day, one for breakfast and one for dinner. This amount may vary if you also give your cat some fresh or dried food.


FancyFeast had some sort of magic power over our cat who would eat no other canned food. It did make shopping easy.

It is low in carbohydrates which is good for diabetic cats. Our cat became diabetic in his senior years. The vet was happy for Fancy Feast to remain the dietary choice for our cat.


These small cans can be hard to open. The cans with gravy can be messy. Cat food on fingers – ugh


Typically the boxes come in a 12 pack or a 24 pack. Because we used two cans per day, I always bought in bulk as a 12 pack doesn’t last long. It make sense to have a supply or have on autoship.

Is it okay for cats to eat raw fish? Yes? No? Um? Maybe? Do you know the answer?

2. Instinct Grain Free Salmon Recipe

Instinct Original Grain Free Real Salmon Recipe Natural Wet Canned Cat Food by Nature's Variety, 5.5 oz. Cans (Case of 12)

The first two listed ingredients in this food are salmon and salmon broth.

There are added vitamins and minerals including Thiamine.  

This brand is grain free and the company prides itself on using healthy natural ingredients. Here are the most recent reviews​​​​​​ of this product. It is worth reading the reviews as some ​are quite detailed.  Where there is a negative review there has been follow up from the company. ​While we might expect our concerns about a product to be​ acted upon, they are not always, so this is a positive point for the company in my view.

This is a pate style food so if your cat prefers food with gravy, a suggestion is to mash the food and add some liquid, water ​or broth.


Suitable for all life stages of a cat.

This is a good alternative for cats that are allergic to chicken. Chicken is an ingredient in many cat foods.

The product is manufactured in the USA.


Some cats don’t like this flavour – this is a bit hit and miss with cats I’m afraid.

Some cat owners think there is too much liquid for a pate style food.


This food is pate style. The calorie content is 1,057 kcal/kg, 90 kcal/3 oz can, 165 kcal/5.5 oz can. You can choose flavours other than fish – rabbit or chicken. This food has a fat content of 26.25%, carbohydrate content of 3.33% and sodium content of 1.13% on a dry matter basis.

3. Rachael Ray Wet Cat Food – Ocean Lovers Pack

RACHAEL RAY NUTRISH Natural Wet Cat Food Variety Pack, Grain Free, Ocean Lovers, 2.8 oz Tubs, Pack of 12

This ​​cat food is grain free.  See what people say about this cat food. This is a link to the most recent reviews of this product and only to the Ocean Lovers Variety Pack. Overwhelmingly the reviews are positive however it is definitely worth scanning the reviews as sometimes there is a comment that you can personally relate to about your cat.

Th​is fish based cat food does tick all the boxes as far as no artificial colors, preservative​s, ​flavors​, ground corn, wheat or soy ingredients.  


Fish is the number 1 ingredient.

Added vitamins, minerals and Taurine.

Point to Consider

This food is made in Thailand. I am not suggesting that this is a Con. I have visited Thailand 4 times and love it. In these days and uncertain times, some people are preferring to buy closer to home.


The cans are 2.8 oz. They are available in a pack of 12 or a pack of 24. The flavors are Ocean Fish, Chicken and Shrimp (note the chicken) and Tuna.

Ocean Fish-a-licious: Ocean Fish, Water, Tuna, Vegetable Oil, Powdered Cellulose, Tricalcium Phosphate, Salt, Guar Gum, Xanthan Gum, Celery Powder, Potassium Chloride, Choline Chloride, Magnesium Sulfate, Taurine, … see more ingredients

4.  I And Love And You – Oh My Cod Fish Based Cat Food

"I and love and you

If you are looking for a natural product this may be what you are looking for in a fish based cat food. The food does not have any artificial preservatives or flavors, no additives or fillers and no wheat, corn soy or rice. It is also grain free although several other varieties reviewed here are also grain free. In this food sweet potato is used instead of grain.

As a cat’s diet should be primarily protein based I was satisfied to see that the sweet potato, being a carbohydrate is listed eleventh in the list of ingredients followed mostly by supplements, so the carbohydrate level would be assumed to be low.

Protein is number one on the list so a tick there and interestingly the food also contains some vegetables and fruits. Cats don’t actually need fruit and vegetables however the food is approved by a holistic vet and pet nutritionist and fruit and vegetables may be a preferable inclusion as opposed to other filler type foods.  This food is classed as natural but not classed as organic.

​Read the reviews for the cod recipe.  As with most things there are some positives and negatives, some cats don’t like the product and others love it.  One of the main things I look for is safety and there are no reports that I could find of this food causing any issues regarding health. One ​person contacted the company as the cats did not like the product. The company refunded the money without the product having to be returned.

​It is wise to go with a tried and trusted brand when buying fish for your cat in cans.

In the end we all have to make our own choices. The products reviewed are ones that I would feel comfortable using and indeed as I mentioned our cat had a steady diet of Fancy Feast (amongst other things) for many years.  

With fish it is ​important that thiamine is added to fish based cat food. ​​If you have any concerns about feeding fish to your cat raise it with your veterinarian next time you visit.

It is made in the USA.

Full of healthy Omega 3’s and 6’s.

Formulated by an holistic veterinarian.


The cans may smell fishy. Despite our best intentions, some cats will turn up their noses at this food.

This food does contain vegetables. Cats don’t normally eat vegetables.


This food is grain free and also has zero by-product meals, soy, artificial preservatives, flavors, or colors. The can shown here is a cod recipe however there is also a tuna variety and two different salmon recipes. There is the option to buy packs of 12 or 24 and 3 oz or 5.50 oz cans. Cats are spoilt for choice.

Cod, Chicken, Chicken Liver, Fish Broth, Spinach, Cranberries, Apples, Carrots, Natural Flavor, Guar Gum, Sweet Potatoes, Alfalfa Meal, Ground Flaxseed, Taurine, Salt, Potassium Chloride, Cassia Gum, Xanthan Gum, Choline Chloride, Dl-methionine, Salmon Oil (Preserved With Mixed Tocopherols) … see more ingredients

5. WholeHearted Wet Cat Food Variety Pack

This is a Petco’s brand. In this seafood trio there is no corn or wheat or grains of any type. As with fish for human consumption this food contains antioxidants which help support the immune system and Omega 3 & 6 fatty acids.

The first ingredient is protein which is essential in a cat’s diet and should always be at the forefront of whatever the cat is eating.


This cat food is a good price.

The first ingredient is seafood.


The can sizes are 2.8 oz which is quite small but perfect for smaller sized cats.


This is a Petco’s brand. There are three different seafood choices in this pack, Tuna, Salmon and Ocean Fish. On Petco’s site you will find other fishy flavor combinations, some in pouches and some in cans. The cans are 2.8 oz.

This is a comprehensive list of foods that cats should eat sparingly plus foods that cats should definitely not eat.

Our Recommendation is…

1. Fancy Feast Seafood Feast Variety Pack

​We care that the food​ we eat has quality control in preparation and we should expect the same for ​the food our cats eat.  Every now and then cat food has to be recalled and that does happen with food for humans also.  We need to be diligent about the food we give our animals.

We choose Fancy Feast for fish based cat food for the reliability of the product and the secure knowledge that this product  has been used by us on an almost daily basis for the best part of 18 years.

In addition the cat loved Fancy Feast. To say we supported the Purina company would be a fair statement.

This food was entirely suitable for senior cat.

fish based food for cats
I can smell seafood dear. I hope it’s for dinner!
