I have a 10 year old female cat named Ruby. Yesterday I noticed she wouldn't urinate in her box,and kept trying to go outside of it. She peed on the floor outside the box and I noticed blood in her urine, and she looked to be in discomfort, so I took her to the vet right away. The vet said it looks like a UTI,but they needed to take urine from her. They weren't able to collect urine to analyze, but sent her home with pain medicine and told me to bring her back this morning. I brought her in around 10 am, and they still couldn't get any urine from her. So she has to stay over night. I miss her. I just want to hold and comfort her. This is the first time she's ever stayed at the vet's over night.
