I was shocked to hear about Chinese scientists cloning animals and even more surprised to hear how many people are waiting to get the exact same dog they already have.
この場合、次のような言い方ができるかと思います。
ーI was shocked to hear about Chinese scientists cloning animals and even more surprised to hear how many people are waiting to get the exact same dog they already have.
「中国の科学者が動物のクローンを作っていると聞いて驚いたが、多くの人が既に飼っている犬のクローンを待っていると聞いてもっと驚いた」
to clone animals で「動物のクローンを作る」
ご参考まで!
