Side point here.
I seem to remember an article from several decades ago, or it might have been in one of the blood booklets, that pets shouldn't be given food with blood in it because that would be a violation. That struck me as odd since animals in the wild often eat the blood of other animals naturally.
Using fertilizer with blood in it was a violation too.
Again, that's odd, since an animal killed for food was to be bled before the meat was eaten - the blood was to be "poured out onto the ground" - therefore it would naturally have become fertilizer.
Even as a fully believing Jehovah's Witness at the time these things didn't make sense to me. I should have paid better attention to my inner instincts.
So many man-made rules in the JW religion.
Edited to add:
The no-blood-transfusion policy is mainly based on the idea of not eating blood, which applied only to humans. Animals were not Biblically prevented from eating blood, so what is the scriptural basis for denying a blood transfusion for them? Go figure.
