To be fair that’s an improvement over the previous test since you could reuse the frogs while you had to kill the rabbit. Even older ones involved peeing on grain. We’ve known that there was something different about the urine of women when they are pregnant for a shockingly long time, but couldn’t explain exactly what in any real detail until fairly recently.
I didn’t know about the grain or rabbit tests.
At least the rabbits got off the hook when the frogs presented themselves as a better option, I suppose.
