Quick Transmigration Main God, I'm Your Cat

She was a cat raised by a High God. When the Supreme God descended to the mortal realm to undergo trials, she sold her soul to an old witch just to follow him, sharing life and death and being reborn together. First world. She was reborn as a commandery princess. Her mother was a venomous consort, and her father was a prince. Growing up in this household gave her plenty of chances to put her mouse-catching and bug-hunting skills to use. At last, she met the Supreme God. He had been reborn as the Imperial Preceptor, able to divine the future and command the wind and rain. On the road, she tugged at his sleeve and called him Master, but he shook her off. She pounced on him again. Purring, she rubbed against his sleeve. Her parents asked if she liked the Imperial Preceptor. She said she did. They asked if she wanted to marry him. She said no, she only wanted to be his pet. Second world. She was a nobleman's daughter, and he was a merman. Wow, a fish. I want to eat him... Third world. She was human, and he was a vampire. Wow! Master, come drink my blood! Drink as much as you like, it's all yours! [The kitty is adored by everyone and loved wherever she goes. She is devoted to staying by the Supreme God's side, and in the end, she is showered with affection.]
