Is it possible to splice the dna of a human nd the dna of a cat? To make it multiply in-side of someone(me)?

It is possible to splice a limited amount of DNA from one species into the cells (DNA) of another species but whether the recominant DNA would be expressed could not be predicted. Even if this could be done with some of your cells, there is no way to get this recombinant DNA to become a part of a high percentage of the approximately 100,000,000,000,000 (100 trillion) cells comprising your body.

Ron Baker, Ph.D.

Well, yes, it would be possible. But gene splicing usually involves one or a few genes only. The gene will be the directions for making a protein, and hopefully that protein would not be recognized as foreign by your body and be rejected. Even if it is theoretically possible, I would wonder why one would WANT to have a cat gene spliced in, because humans and cats already have many genes in common, and just having one or two genes from a cat would not give you cat-like characteristics.
