Hi! My rat Missy can hold her urine/droppings for half an hour or more when handled, while my other rat, Cookie, can hold it for about two minutes whenever I handle her. My mom thinks she may have a Nervous Bladder, but I thought might as well be safe and check in with some experts. Does Cookie have a bladder infection or something? I try to handle my rats an equal amount of time, but I feel like I hold Missy more because she can hold it in.
