おっしゃられている内容は、既にいくつか回答が出ていますが、
She was originally a stray cat. I picked her up and took her home.
のように言うこともできます。
originallyをa stray catの中に入れるのはおかしいので、外に出す方が良いです。
took her homeのherは目的格のherです。
my homeと入れるなら、took her to my homeとすることは出来ます。
また、
herを省略して1つだけにする場合、最初のherを省略して
picked up and took her to my homeという言い方は出来ると思いますが、
2つ目のherを省略して、
picked her up and took my home
みたいにはしないです。
以上です。
少しでも参考になれば幸いです(*^_^*)
