Daily target: 90 mg EPA+DHA for a 4.5 kg cat.

  • At 4.5 kg, the target is 90 mg of EPA+DHA per day for general wellness.
  • That breaks down to roughly 54 mg EPA and 36 mg DHA.
  • Less than half a capsule is needed daily - your product is well concentrated for this dose. Consider giving it every other day and confirm the schedule with your vet.
  • Fish oil results typically take 4 to 6 weeks to appear. Start with a lower dose and increase gradually to avoid digestive upset.

Next stepConfirm this dose with your vet before starting, especially if your cat is on other medications or already eats an omega-3-enriched prescription diet.
