Google A.I has proven my protocol to be possible. If an enuceated Human egg is given the nucleus of a somatic Human-Cat hybrid cell. The result embryo would be mostly Human but significantly Feline. A Cat Girl is likely. Also the Armasloth is a realistic outcome if the protocol is applied to Sloths and Armadillos. I quote A.I now...

If an armadillo-sloth hybrid somatic cell nucleus were implanted into an enucleated armadillo egg, the resulting embryo would likely be an armadillo, but with genetic material from both species. The egg's cytoplasm and the enucleation process would likely favor the expression of the armadillo's genome, but some sloth characteristics might be expressed, especially if the sloth DNA is highly active.

I have finally broke the law of nature.
