It's been awhile I heard cloning Dogs were an extreme challenge, according to that they did the first cloned dog in 2005. Nice work.
Glowing pets I think will be an expensive purchase, which is ok, considering there are some people that will get the pet just to show off and fail to be a good keeper.
The spider goat is a successful experiment. Not as cute as these little guys, but defiantly holds it's value.
