It was white. And the shape confused me...until I heard about whip worms; it could have been a pinworm, possibly too...it was extremely tapered for about 1/3 of it's overall length...it didn't gradually narrow, it just went from big to small. I think same color throughout...I literally caught it floating in the air like a hair. I'm extremely sensitive to things flying around me. But a flying worm BLEW my mind...but then I thought well, yeah, any freshly hatched parasitic worm is gonna be small enough to do that...it just hadn't occurred to me, I guess. No one talks about it.
Interestingly, when my dog first started magnesium baths (I just let him get in the tub when I'm done...3c epsom and 1 box baking soda) He apparently vomited up some really big worms while I was gone one day. I found some amazing stuff in the vomit, but the main worm was GONE. It left an imprint on my floor though ...looked like something out of a Steven King novel, but I'm gonna write it up instead, lol. I just wonder if it was the magnesium that caused him to do that. I hadn't wormed him.
