Current technology has clones being born solo.

"I'm not so sure about cats," she says But when it comes to dogs, they have to have litter exposure to grow up normally.

Fiester, The Pennsylvania bioethicist, shrugs this argument off.

If the clones turn out to be "animal monstrosities", she says, "that'll be the end of the pet cloning business".

Finally, critics of pet cloning say there is the issue of the millions of a animals who don't have homes that are living on the streets or housed in shelters.

If Genetic Saving & Clone can create animals that pet owners are happy with - animals that aren't sick or compromised and behave in ways similar to the original - the business will succeed, Hawthrone says.

His scientist also is looking into how to enhance pets - how to make them live longer and healthier.

"Our clones will be better than normal," he says. "Clones are going to become the preferred pets."
