Care-guide bands are educational. Dog senior care begins at 75% of estimated lifespan, not a universal birthday. Cats are senior above 10 years; the 15+ page is an editorial subdivision. Human-age equivalents do not determine clinical stage.
Kitten care tips
- Vaccinations: Complete the kitten vaccine series and parasite prevention.
- Litter & play: Establish litter habits and provide plenty of interactive play.
- Socialization: Gentle handling now builds a confident adult cat.
