Example Calculation
4.5 kg Adult Cat with Arthritis
Cat Details: 4.5 kg (9.9 lbs) indoor cat
Condition: Osteoarthritis affecting joints
Dosage Goal: Anti-inflammatory support
Supplement: Standard fish oil capsules (300mg EPA+DHA)
Calculation Results
Daily Dose: 4.5 kg × 75 mg/kg = 337.5 mg EPA+DHA
EPA Amount: 337.5 mg × 60% = 202.5 mg EPA
DHA Amount: 337.5 mg × 40% = 135.0 mg DHA
Capsules Needed: 337.5 mg ÷ 300 mg = 1.1 capsules daily
Practical Dosing: 1 capsule daily (slightly under target)

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.
