This calculator works for:
- Pet health planning - Understand your cat's life stage and health requirements
- Veterinary care - Determine appropriate wellness schedules and age-specific screenings
- Life stage awareness - Recognize when your cat becomes a senior requiring special care
- Breed considerations - Get accurate age conversion for all domestic cat types
