"And I always talked about the importance of signing our organ donor cards.
"But this year, for the first time in my life, I've decided not to sign it. Here's why.
"I realised how despicable society is, how many evil people are out there.
"Especially since coming to TikTok, even more so.
"And I've decided there's no way on earth I want any of you to ever get my organs if I die.
"The only people I would ever want is vegan animal rights activists.
"Because I will give those organs to those people and I know they will not be murdering animals to put into that body.
"The rest of you will continue to live and just keep murdering animals.
"So I just wanted to let you know that it's really disappointing that it's come to this."
Miss Kadie's video has amassed hundreds of comments castigating her decision and calling her "heartless" for refusing someone in need the chance to live.
"Thank you for condemning someone to death because of a bunch of 'evil people'," one said.
"Tell that to the next child who needs a new organ."
Miss Kadie, whose TikTok biography reads "Miss Kadie is on TikTok to help animals & all who are oppressed" favours hashtags like #meatismurder and #dairyiscruel.
She has made scores of pro-vegan videos starring herself and her dog Bella, who she feeds a vegan diet.
In August this year Miss Kadie, who claims she has received death threats for calling out non-vegans for not ditching meat, called police after teenagers broke into her home, she said, to steal Bella.
