Q. Pooing 4-5 times daily, soft smelly stools, weight loss. Eatign and drinking well. Seems happy in self

It could be as simple as a dietary indiscretion, meaning she might have gotten into the trash and eaten something that didn't agree with her.

As an older cat, hyperthyroidism or diabetes can cause weight loss with a good appetite.
