You know, the more you describe it, the more it sounds like a UTI. Such frequency, going small amts. throughout the day/night, are classic symptoms. UTI's can be treated successfully so easily and relatively inexpensively...I hate to say I hope that's it, but all things considered, I do. Is her diabetes under control? Are they able to check her blood sugar? If her sugar's high, she may be needing to go more often, though usually with diabetes it's larger amounts. Your parents know that, I'm sure. They sound like very devoted furparents who care greatly for their friend. I'll be thinking of your family and sending positive thoughts their way that a solution can be found.
