Cats need these fatty acids to maintain optimal health. It helps with brain function, cognitive ability, memory and learning capacity in cats. It also acts as a natural anti-inflammatory agent. These fatty acids are usually found in fishlike mackerel and trout which are fatty and live in cold waters. You can also find them in some shellfish like mussels or oysters. (2)

Can Cats Have Fish Oil?

Cats can and should have fish oil, but the real question is will your cat have fish oil without making a big fuss about it? Maybe or maybe not. Cats are usually fussy about eating medicines. Hence, there are multiple options available for you to feed fish oil to your cat. They include – 

  • Liquid fish oil that can be added on top of dry kibble or treats

  • Fish oil capsules that come in a soft gel format

If your cat keeps running away, you can choose natural foods as well to incorporate fatty acids into your cat’s diet. Your options include – (1)

  • Salmon

  • Mackerel

Ensure that you choose a high-quality and responsibly sourced option. Read the label to ensure the product is tested thoroughly for contaminants like heavy metals and oxidation. Avoid fish capsules or other products that come with additional vitamins A and D. Cats can easily absorb these vitamins and hence excess consumption of them can cause stomach problems for them.

Choose a product that can provide all the benefits to your cat in a small serving size so that you can easily incorporate it into their diet. The common serving size when it comes to a capsule is 1 capsule per day, 1-2 fortified treats per day or 1 teaspoon of liquid fish oil for cats.  

Can I Give My Cat Human Fish Oil Capsules?

No. Never feed any type of supplements made for humans to cats or any other pet for that matter. The concentration of ingredients can vary significantly, and this can cause major problems for your cat. 

One of the most common ingredients in fish oil supplements made for humans is a sweetener called xylitol. This can potentially be poisonous for cats. They might even have added flavorings and added vitamin D. Even these can harm your pet’s health. (3)
