Today while looking at one of my guys that got blocked up last week, which required a trip to the emergency hospital at midnight, I noticed some blood in his urine. It was faint and pinkish, but certainly blood. I know it's common for cats to have blood in their urine after being blocked, but a week afterwards? He's been on antibiotics, and was hooked up to fluids and catheterized for over 24 hours, so he was flushed out well. Is this out of the ordinary granted his situation? The vet told me I caught the blocking relatively early.
