as often as you feel the need too...it depends on how much fluid you intake daily.
The average adult bladder holds approximately 1 pint of liquid so you should urinate as many times as your bladder is filled daily. This means, if you drink 2 pints of liquid you should urinate at least twice before you could drink anything else, unless of course you wanted to urinate on yourself.
1-3 depending on how much they have to drink.

You should take in atleast 2000-2500 ml of water a day to maintain healthy fluid balance in the body. You normally urinate about 1500 ml of that.

The kits (babies) still urinate but they are small animals and don't go often. My Flemish Giant didn't urinate a lot when he was a kit but since he's grown he goes more often.
