Penny has these enlarged lady parts and the vet said they'd make her more prone to UTIs. So we weren't suprised a the other week when we decided we thought she had a UTI and the pee test showed white blood cells. But we were suprised when the vet said her pee was too diluted, which could either mean something perfectly harmless like she drank a lot of water before she peed (which I suspected) or a kidney function problem. So we made a plan of action that she would go on antibiotics and then when they were done we with them we would bring in a first thing in the morning pee sample which hopefully would show that the pee wasn't diluted and the infection was gone.
On Sunday Penny finished her 10 day dose of antibiotics, and so on Monday morning I collected her first pee and took it to the vet. I just got a call from the vet and she said it looked virtually the same as the first one: the pee is still diluted and there was still bacteria present.
So now I have to take her to the vet in the morning and they have to put a tube into her to get pee straight from her bladder (to make sure the bacteria wasn't from her skin of the cup, etc), and take a blood test (to check her kidney function). I am worried now because the vet thinks she might have either a bacteria-resistant infection, a congenital kidney disease, or both.
