Selkirk Rex age in human years

Enter your Selkirk Rex's age in the calculator above. We use a science-based formula for cats — not the old "multiply by seven" rule — and show life stage and lifespan context with your result.

Lifespan varies by species and care. Use the calculator above for age and life-stage context.

Pick Selkirk Rex (already selected here), enter age in years or use date of birth when available, then calculate. You'll see human-year equivalent, life stage, and how far through a typical lifespan your pet may be.
