Why Do Cats Live longer Than Dogs?

It seems puzzling that on average cats live longer than dogs (15 rather than 12 years). Normally larger animals like whales and elephants live longer than small ones such as flies and mice. On average small dogs also live longer than large ones.

The video suggests that because small animals are more likely to be caught by their prey, they need to make up for this by fitting their lives into a shorter timespan. Cats may buck this trend by being cleverer at surviving predation than dogs and so have naturally evolved to have a longer lifespan.

The oldest cat that ever lived is recorded as living 38 years and 3 days according to the Guinness Book of World Records who validated the record – this was an american cat called Creme Puff who lived from August 3, 1967 to August 6, 2005. The oldest ever dog was Bluey, a sheepdog from Australia who lived to 29 years.

The good news is that both cats and dogs are now tending to live longer than they did a few years ago. It may be that in the future more of our cats will live to extreme old age like Creme Puff.
