Understanding Fish Oil for Cats

What is Fish Oil?

Fish oil is derived from fatty fish tissues and is a rich source of omega-3 fatty acids, specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These are essential fatty acids that cats cannot produce on their own and must obtain through their diet.

EPA vs DHA

  • •EPA: Anti-inflammatory effects, joint health, skin conditions
  • •DHA: Brain development, eye health, cognitive function
  • •Ratio: Most supplements contain 60% EPA and 40% DHA

Dosage Formula

dose(mg) = weight(kg) × multiplier

  • General Health: 40 mg/kg (maintenance dose)
  • Kidney Disease: 112 mg/kg (research-based)
  • Arthritis: 75 mg/kg (anti-inflammatory)
  • Skin Issues: 60 mg/kg (dermatologic support)
  • Cardiac Support: 85 mg/kg (heart health)

Important: These doses represent total EPA+DHA combined. Always account for omega-3s already present in your cat's regular diet to avoid overdosing.
