Scientists explain why cats live longer than dogs

unian.ua (Ukrainian)

Cats live longer than dogs due to a higher brain-to-body ratio and a more robust immune system. Scientists found that a larger brain size correlates with stronger immunity and longer lifespan across mammals. Cats' evolutionary path as solitary hunters contributed to their brain development and immune efficiency. This enhanced immune system effectively removes damaged cells, controls infections, and inhibits tumor growth, leading to lower cancer rates and slower inflammation in cats compared to dogs.
