Thanks everyone *hugs* to you all What a frustrating circumstance this is. Well, the good news is that my mom picked Scooter back up from the vet and brought him back to my home, so he's not having to stay overnight this time. What gets me is now, after the vet diagnosed a bacterial infection with no crystals last week...diagnosed crystals today. I asked if I needed to maybe feed Scooter a special diet last time, and they said no, but this time, they have prescribed a special low magnesium diet that he's going to have to eat for the rest of his life. Hopefully this will help in reducing the possibility of a recurrance! They said that the food should cure it. Hopefully it will help! We've been to several different vets on several occasions, so hopefully one of these is bound to help! Unfortunately UTI is such a hard thing to diagnose, since it comes in multiple forms all with the same symptoms. The links at AskJeeves were pretty informative. Thanks for posting those Spencer.
