Meow Meow, Woof Woof

A cat finds a tiny puppy and works hard to raise him. After dying unexpectedly, the cat is reborn and finds the same miserable little puppy again, raising him once more, only to end up getting swept off his feet. That's the story.

P.S. Don't ask what the title means. The protagonist came up with it himself, so go ask him.

Also: How am I supposed to write the romance? TAT

Note: The wealthy family is just a backdrop and doesn't really matter. There are no schemes over inheritance or anything like that.
