The rabbit died because it had to be autopsied to inspect the ovaries. Whether a woman was pregnant or not didn't determine whether the rabbit died.
> FWIW the rabbit always died whether you were pregnant or not :(.
It's not that an injection of urine if a pregnant woman kills the rabbit.
It's like the rabies test on the brain. We cannot look at the brain before you're dead, because the act of looking at it would kill you.
I can see how this might be read in two different ways now.
