This is weird, i always assumed all other mammals went through it too. Why wouldnt they?
They don’t live long enough to go through menopause. Ever met a female cat that lived into her 50s?
We may soon discover that orcas also experience menopause as soon as some daring team of whale biologists carries out a similar study collecting orca pee.
Some whales have menopause too I think.
Orcas do, and their behavior fits the grandmother hypothesis pretty well.
And elephants.
That wouldn’t surprise me at all. They certainly live long enough. 
Ah, I see. That's interesting, never realized this! I guess I just thought mammals had similar reproductive setups (aside from different gestations and number of children etc) But I really have no idea haha.
Maybe because most mammals don't menstruate. Only humans and a few others do, like bats and some apes.
All placental mammals menstruate, most of them just reabsorb the endometrium internally instead of shedding it. Most mammal females are also not in heat all year round.
