That's just crazy.
I love my pets as much as the next person........ ..but I certainly would never consider cloning one of them.
Not only is it a huge expendature (which as stated could be used better elsewhere), but at this point they don't know if there are health problems associated with cloning. From my understanding, the cloned sheep don't live that long and offspring of cloned animals generally have problems (I think......i could be remembering incorrectly).
I would much rather remember my pet as an original, and have them live in my memories rather than have them relive in a new body. Not to mention it would be very painful to watch an identical looking pet walking around that wasn't identical (mentally) as my previous pet.
