I always wanted a cat but never had one as a child. Decades later, I used Doubao API to merge my childhood photos with my cat's images, then built a reusable Django app (django-doubao) that does AI image fusion and image-to-video generation. Here's how it works and why I built it.

The Empty Space

When I was a kid, I longed for a cat. My mother wouldn't allow it. I pressed my face against the neighbour’s window, watching their tabby stretch and roll in the sun – a hollow ache in my chest.

Only after forty years did I finally get my own cat. But then a new sadness crept in: I couldn’t grow up with her.

So I devised a trick.
