What causes Polyuria?

[Bokkapooh]

As the title says, I'm curious if anyone has any ideas that causes polyuria?

My cat Morag has it but that's because she take diuretics because of her heart condition.

In humans it can be a symptom of diabetes.

I was going to say diabetes is one cause. Kidney problems and infections are another. A diet high in fresh produce could cause excess urine, too. Metal toxicity might be another?
