Two kittens have been born using a new cloning method that may be safer and more efficient than traditional methods, according to Genetic Savings & Clone.

The company used a new method called chromatin transfer that tries to produce a cloned embryo that more closely resembles a normal embryo.

It involves dissolving the outside of the nucleus of the cell to be cloned and removing certain regulatory proteins from the chromosomes and the proteins around the chromosomes. The entire cell with its permeable nucleus is fused to an egg cell to create the clone.
