Cornish Rex Feeding Calculator
Cornish Rex owners often ask how much to feed their cat each day. Adult Cornish Rexs typically weigh between 2.5 and 4.5 kg, though individual metabolism, activity, and health status all influence true calorie needs. This Cornish Rex feeding calculator uses veterinary RER and MER formulas to estimate daily calories and food portions based on your cat's current weight, body condition, activity level, and life stage. Whether your Cornish Rex is a growing youngster, active adult, or senior companion, portion guidance should be adjusted as weight and energy change. Use the results alongside regular body condition checks and your veterinarian's advice—especially if your Cornish Rex has breed-related health considerations or is on a weight-management plan.

Cornish Rex Feeding Tips
- Weigh your Cornish Rex monthly and adjust portions if body condition drifts from ideal.
- Split daily calories into three measured meals to support steady energy and digestion.
- Choose a complete diet appropriate for your Cornish Rex's life stage (puppy/kitten, adult, or senior).
- Track treats and table scraps—they can add 10–30% of daily calories for many Cornish Rexs.
- Increase portions gradually during growth or high activity; decrease slowly for weight loss.
- Small Cornish Rexs have higher metabolic rates per kg—small errors in portion size matter more.
- Encourage hydration with wet food or fountains, especially important for Cornish Rex urinary health.
Health Notes
- Typical adult Cornish Rex weight: 2.5–4.5 kg (small cat).
