Yeah, that means the antibiotics are working!

And a big definite YES, absolutely keep up for the next 6 days. Antibiotics will usually clear up the symptoms in 24-48 hours, but you need to do the entire ......(can't think of the word)....regimen...that's the word to make sure the UTI is completely cleared up. It's pretty much a guarantee that if you stop now, Max will be back at it again before you get home from work tonight. You can still try and get a sample although since it appears to be working, they might not be able to tell as much from it, but then again they may so I would say if you can get one, get it, otherwise just wait and hope it's just the UTI. If it's crystals, I'm sure it'll be back real soon.

Way to go Max Man!
