First, I would ask what you mean by "hold in her urine". It is normal for a rat to urinate while walking sometimes or when you are holding them.

No, because in a related question, I answered that is impossible to urinate or have the urge to urinate during sex and if it happened, whatever going on wasn't sexually stimulating to the person.
I don't think you can unless the cat wants to. Cats only urinate where they think it's safe and where it won't get in the way of anything. They usually urinate in sand pits, or boxes, or just places they know they are allowed to 'urinate' in!
