The average mouse can live for about 2 years, the average hamster can live for about 3 to 4 years
I’m lizard or a frog of a similar size can live much longer, 5 to 10 years, twice that long in captivity
Overall, reptiles generally live longer than Mammals
How does this happen
In: Biology
There are some hypothesis that when lizards were the top dogs 65 MYA, they were advantaged to live long, where as the mammals (that were all rodent-like) had to breed a lot to survive. This means living longer isn’t as important.
This has carried through to modern day.
There isn’t any solid evidence for it. But there isn’t many better hypothesis
