Everything about the lifespans of races is only speculation except for two things:
-Elezen live longer than Hyur, but not by much.
-Lalafells 'stop' aging at some point and can live beyond the hundred years. (This is based on an NPC in 1.0, I think, whose dialogue implied he had been alive for 120 years at least).
Also, please note that Miqo'te are not cats. They are humans with feline parts. Making them live less or more than Hyurs is arbitrary and speculative.
As a rule of thumb, I'd go with "everyone lives between eighty and a hundred years", except for lalafells, who apparently live longer.
