I think you are missing something. You can keep those weaker birds alive and avoid keeping cats cruelly locked indoors. You could just avoid keeping cats entirely.
My cat is perfectly happy being an indoor cat with supervised outdoor time. She’s more upset when she gets closed out of the bedroom than she is about not being able to go outside whenever she wants.

I don’t know what kind of cats you’ve met but mine are perfectly content with being inside.
