Poor Oreo! After a blockage, cats might only urinate small amounts frequently, but as long as he's peeing, that's positive. I would expect to see some blood, as he has sustained trauma to his urethra with the blockage and subsequent unblocking. I would continue to monitor him very closely, as reblocking can occur 7-14 days from the time of discharge. This is because the urologic syndrome that led to blocking in the first place is still continuing and as long as the episode continues, blocking is a possibility. Any loss of appetite or vomiting should be reported to your veterinarian at once. If there is any concern about reblocking, your vet can determine fairly easily if the cat has re-blocked.

    As long as he is passing urine and doesn't seem to be straining to urinate than it is probably normal. It is not unusual for cats to go small amounts frequently after being blocked because their urethra is inflammed. I am also not surprised that there is blood and particles in the urine and that should clear up in a few days. If you have any concerns or your cat is straining than he should be examined by your vet to make sure there is no blockage. If he stops eating or begins vomiting please call your vet.

    Unfortunately, this indicates that Kota's urinary problem is persisting. They often get this bladder inflammation due to stress, which can be very difficult to treat for sometimes. I recommend taking him back for a recheck with your vet. They may want to prescribe a different medication or do additional testing. It's not an emergency at this time, but if he stops urinating, or is noted to be straining to urinate, then he should go to the emergency clinic. Otherwise, you can take him back for a recheck during normal business hours. I hope that helps and Kota gets better soon.

    It's not necessarily because the pain medications are wearing off but this condition can get worse before it gets better even with treatment. he seems to be well covered medication wise but as it's a male the risks of blockage are always very high so you will need to monitor him closely, if it seems to not be getting better you will need to take him back to the vet ASAP.

    Thank you for submitting your question regarding Mr. Luck. I am assuming you are referring to a urinary catheter being placed in response to a urinary blockage. If this was the case, the urine can appear bloody afterwards due to residual inflammation and trauma to the urinary tract. As long as he is still able to urinate, this is likely a normal finding. However, I would call his veterinarian and pass along this update on his condition and to ensure that they do not feel he requires further treatment. I hope this information helps!
