You know what, I start thinking about it before. Those who are taking care of their dogs and lost them, they are into cloning. They want their pets to come alive again. Cloning doesn't mean they will going to be the same pet again, but seeing them again, the one that really looks like their pet, it gives them peace. Some are against it because once something or someone died, they are all gone. You should respect their existence here on earth and only remembers the good memories you had with them. It is such a bad idea to make another one. Even some are suspecting that when you clone something, the other one will look the same but it will be the bad side of the original. It is just an estimation. Actually, cloning already happened in some countries, with animals like goats.
