Fish Oil Dosage Calculator for Cats

A general daily omega-3 reference for cats. Confirm the amount and product with your veterinarian — cats are sensitive and dosing should be conservative.

How the Math Works

The Fish Oil Dosage Calculator for Cats uses a straightforward mathematical formula to estimate the appropriate amount of omega-3 fatty acids (EPA+DHA) your cat needs. The calculation is based on the formula: EPA+DHA amount = cat's weight in kilograms multiplied by a goal factor. This goal factor represents the recommended daily dosage of omega-3s per kilogram of body weight, which is generally established by veterinary nutrition guidelines. For example, if the goal factor is 0.1 mg/kg and your cat weighs 4 kg, the calculation would be 4 × 0.1 = 0.4 mg of EPA+DHA per day.

Practical Applications

To use this calculator effectively, first determine your cat's exact weight in kilograms. If your cat's weight is in pounds, convert it by dividing by 2.2 (for example, a 10-pound cat equals approximately 4.5 kg). Next, select or confirm the appropriate goal factor based on your cat's specific health needs and your veterinarian's recommendations. Multiply your cat's weight in kilograms by this factor to determine the daily EPA+DHA requirement. You can then refer to your fish oil supplement's label to determine how much liquid or number of capsules will provide this amount.

Day-to-Day Use

This calculator helps simplify the often-confusing process of supplementing your cat's diet with fish oil. By providing a personalized dosage amount, you can ensure your cat receives the therapeutic benefits of omega-3 fatty acids without risk of over-supplementation. This is particularly helpful for cats with arthritis, skin allergies, or heart conditions that may benefit from omega-3 supplementation. Having a clear daily target makes it easy to track and maintain consistent dosing, which is essential for achieving the desired health outcomes over time.

Worked example

4.5 kg cat, skin & coat → ~135 mg EPA+DHA/day.
