In this video, I break down the big question: how long do cats live, and what actually impacts a cat’s life expectancy. On average, most cats live about 10–15 years, and some can make it past 20. I also explain why lifestyle matters so much—outdoor cats face parasites, disease, vehicles, weather, and other animals, which is why many outdoor cats average closer to about 7 years, while indoor cats often reach around 14 years or more. I also cover the other major factors that influence longevity: nutrition, health, and breed. Cats are obligate carnivores, so protein and proper amino acids (like taurine, methionine, and cysteine) are essential, and overdoing treats can lead to obesity and related issues. Then I share my best tips to help your cat live longer: excellent nutrition and hydration, daily exercise and play, yearly vet checkups, early preventative dental care, and mental stimulation—plus keeping your cat indoors for safety. Finally, if you adopted a stray and don’t know their age, I walk you through how vets estimate it by looking at teeth, eye clarity, coat condition, and activity level. I even share the Guinness World Record holder, Cream Puff, who lived an incredible 38 years.
