OK, a spoiled deer will not work , for any reason. It will ask for it's own dredit card on your account and spend it frivolously on Tinks69, vanilla licks, salt licks and maybe even a blow up decoy (heh, heh). It will also live in Quebec and every time it doesn't get it's own way....it'll threaten to separate, without any intention to do so because then it won't be able to use your credit card anymore.
Oh...you were talking about meat? Oh in that case it gets a weird sheen and stink near the bone. It's that easy.
