Many people consider their pets members of the family and are very sad when they die, but what if you could clone your dog, cat or bird?

A scientist in New Orleans, who has proved his ability to clone other animals, is now offering the possibility to pet owners here in Wisconsin.

Scientists have not been able to clone dogs, cats or other pets, but if and when the time comes, several companies will be ready and able to do the job.

The question is: Are you ready to clone your pet? Brett Reggio is betting on it.He is working on his Ph. D at Louisian State University. He's successfully cloned a goat five times and wants to try the process on family pets.  So he started a business called Lazaron. “What Lazaron provides is the first step in the cloning process. ”He said.“It’s for curing and storing the fiberglass cells that will be used for cloning.”

“Your first reaction is yeah! I think I’d like that.” said Donna Schacht, a pet owner.

“I don’t believe you can ever replace a special love,” pet owner Paulette Callattion said.

Most pet owners will tell you freezing your pet’s  DNA in hopes of one day cloning it is a personal decision.

Scientists say that cloning your own pet doesn’t mean that the offspring(后代) will have the same intelligence, temperament(性情) or other qualities that your pet has.
