There's definately the creepy aspect there . . . I don't adopt look-a-like animals for that reason. Though piebald animals don't have the same markings at their clone parents . . .
What really disturbs me about this, is that since people pay for it . . . odds are, no matter how many times you tell them, they think they're getting the same animal . . . or one so similar they won't be able to tell. As we know from human identical twins, however, genetic duplicates are not exactly alike, or even necessiarly all that similar. And clones are LESS alike than identical twins . . . they don't share mitochondrial DNA, they have different womb enviroments (which makes a difference in terms of which genes are switched on). Cloning breeding stock makes some sense . . . but cloning companion animals really doesn't . . . unless people are happy with the illusion. But it stikes me as unfair to the cloned animal . . . and a scam on the prospective owner . . . that on some level everyone wants the dead animal back . . . not a mere genetic duplicate . . .
Now, cloning children, that REALLY gives me the creeps. Unlike a dog, that will never know that you want it to be just like its genetic donor . . . a child will know. And people will be unable to help themselves from wanting this child to be just like the last one . . . . UGH . . .
