Dolly, the famous cloned sheep, did not live as long as expected, and had some health problems. DNA itself changes over the span of many replications (telomeres). The DNA of an adult is different than the DNA of the same individual ar birth. So, a cat created by cloning a 10-year-old cat might start with a genetic age of 10 years.

Thanks for this! My cat of 17 years died in April and I was heartbroken. I thought of getting a clone done but ultimately realized I couldn’t bring her back no matter what I spent. This made me cry reading the article and writing this comment.

Because there is a serious cat shortage??? NOT the actual reason!

Geez..cloned kittens..what's next..
