Is Human estrogen the same as other animal's estrogen?

No idea why this came to my mind, but now I need to know. Is the estrogen produced in a human the same estrogen that is created let's say in a female cat or dog? I imagine i would be extremely close like how humans can use bovine insulin.

Update:

I imagine it would be very close considering humans use bovine insulin.

    Very good question! There are several estrogens in humans (in males too!), and I assume that some other species have some of the same ones.
