The Ultimate Cat Care Guide
A four-part, veterinary-reviewed series for U.S. cat owners — built on the AAHA/AAFP life-stage and vaccination guidelines, the 2025 feline oral-health guideline, CAPC parasite guidance, the 2024 American Heartworm Society feline update, and Cornell and WSAVA nutrition resources.
Quick answer
Excellent cat care in 2026 isn't about buying more — it's about matching care to life stage, risk, and environment. The biggest health wins are routine veterinary exams (every 6 months for cats over 10), life-stage-appropriate vaccines, year-round parasite prevention, body-weight monitoring, daily enrichment, and earlier detection of disease in older cats.
