Well, I wouldn't bother eating it - not because of the supposed parasite problem, which I understandably ignore given my past experiences, but because I have found it to be a major hassle to get any decent amount of flesh from raw rabbit-carcasses, which are much larger than those of mice. I am sure it's easier to get at the flesh if one cooks it as it then hangs off the bone, but in the raw state it sticks to the bone too easily, making it a hassle to remove. So, my rule is to not eat any raw carcasses which are smaller than a raw wild hare(as regards land mammals, not, of course, raw shellfish or raw fish).
