We know larger animals tend to have longer lifespans. But why do big cats(like leopards, etc)have such a short life(about 15 years) compared to humans(about 80 years)?

Question

p.s.Big cats and humans have similar body weights, if not higher.

Larger doesn’t necessarily mean longer life. For example lobsters aren’t particularly large compared to humans but they technically do not die from old age at all. Lobsters can, in theory, live forever, though there are other limiting factors such as disease and predation.
