It sounds like you've hit the nail on the head. The best thing to do at this point is to have a urinalysis performed to see what's causing this UTI problem (bacteria? crystals?) and to have treatment started accordingly. Since you've already changed the diet to help avoid crystals, I would hope that this is from bacteria only. Once she's been started on antibiotics her symptoms should quickly wane.So long as she's still peeing, this can wait for morning. If she stops being able to go, she needs to go to the ER promptly.If my answer has helped you, please take the time today to leave positive feedback for me.
