Thanks for using Petco Pet Education Center, formerly Petcoach. I'm so sorry this happened to Smeagol! The blood and mucous or mineral material you describe are common for blocked cats. Usually the catheter remains in place until the urine is a normal yellow color. Usually 3-4 days is sufficient. Ideally, Smeagol will also get antibiotics to prevent an infection from the catheter and medications for pain and urethral spasm. I recommend calling or visiting your vet if you have further questions. Best wishes to you and Smeagol!

    Hello. Was your cat blocked ( unable to urinate )? If so, it just really depends on the cat. Catheters are generally removed within 12 - 24 hours, so I cannot tell you why your cat still has a catheter. The longer it is in, the more irritating the urethra becomes. It sounds to me like it is time to remove the catheter, so speak with your vet at your earliest convenience to see if now is the time. Thanks for using Petco Pet Education Center, formerly Petcoach.

Male cat had urinary blockage 3 days ago. Catheter set to be removed today but blood (pretty dark) is still present. Should I wait for catheter removal? I'm afraid he will reblock. The vet flushed him 4 times yesterday but still a fair amount of bloo
Poor guy. I’m not sure if the catheter is doing much good if he is having pain and blood still present. It sounds like the catheter should be removed as your vet suggests to see if maybe it is the reason for his discomfort. Also catheters are traumatic in a lot of cases, so this can also be the source of the blood. This is not a simple thing to decide so all factors have to be considered, which I am sure your vet has thought through so it’s best to follow their recommendation on this one. Worst case scenario is that he reblocks when the catheter is removed, but if he is still being hospitalized they can then reinsert the catheter before anything detrimental happens. However, almost cats arts can have their catheters removed after day 2, although each situation can be uniquely different, 3 days seems more than enough time. If you would like to discuss the specifics of your pets case then please don’t hesitate to request a consultation from either myself or another expert here. I wish Ch

Hello, my vet put to my cat the catheter, ( for the second time because the first one he destroyed everything...). After that je destroyed the first one, Klaus lost a lot of blood when he urinated. Now from the catheter he lose a lot of urine, but th
No, it' s not normal . He should be able to pass urine even smaller amounts, not in a continuous stream, with blood but he should pass some ! If he doesn't it means he needs to have the urinary catheter again or he might need a urethrostomy, a more permanent solution to this problem. You need to bring Klaus to be checked over again .

Hi there! Thanks for using Boop by Petco! It sounds like Felix had a urinary catheter placed. If this is the case then yes having some blood in the urine is expected.

My cat was released 2 days ago for urinary blockage. His urine flow is only a few drops, but he goes often. Urine has blood and some particles. Is it
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.

My persian cat had urinary blockage and we brought him to the vet. Found out there were crystals and no big stones seen from the x-ray. They inserted catheter since his bladder was full. There were blood in the urine. And today is his third day in th
If you are not comfortable with the care your veterinarian is providing then moving him to another veterinarian wouldn't be a bad idea. Although, leaving a catheter in for a few days is very important and there may be blood for a little since there was so much inflammation in the bladder. You just have to be comfortable and trust your veterinarian. If you are not and do not then I would recommend transferring the case to someone else. Without knowing everything the veterinarian is doing it is difficult to say if I would provide other care. Thank you for using Boop by Petco.

Hi! My cat recently got his catheter removed. We are prescribed to give him only dexamethasone together with his prescription diet to dissolve the crystals. During the nighr, he was able to pee. This morning he was able to pee small drops. Minutes la
It can be normal if the bladder is empty. It could also be a sign that he is obstructed again. If he’s painful, not eating or his abdomen is firm and painful please take him right in for a recheck. If there’s no urine in another six to twelve hours then that is an emergency and he’ll need to be seen right away for treatment again. Unfortunately sometimes the urethra is inflammed and can close up again once the catheter is removed. Thanks for using Boop by Petco to help you care for Momo.

My cat just got unblocked but now he only pees dribbles and constantly hides. Is this normal?
Yes, this can be normal. Urinary blockage effects a cat's entire system and can make them feel very poorly. When the catheter is removed there is usually a fair bit of inflammation due to the catheter having been in place. The fact that he is producing urine is a good sign. You want to see him continue and start to produce more and more. If he appears to get duller or stop urinating take him back to the vet.

My cat had surgery two weeks ago he had his stitches removed two days ago. Since then he has had a normal pee but occasionally will pee blood. Why? He is eating playing and even drinking water peeing his surgery is called the “PU”
Hello and thank you for reaching out to Boop by Petco. He may occasionally be urinating blood that is leftover from his surgery. He could have some inflammation of his bladder or urethra that is causing some blood to be in the urine. As long as he is acting normally otherwise, he should be OK and these signs should resolve over the next 2-3 days. If the bleeding continues beyond this time or Ares ever starts straining to urinate, he should be seen by your veterinarian. I hope this is helpful!

My 4 y/o cat was recently treated (2 days ago) for a UTI. Slight blockage. Vet said it was caught early enough to not have caused any damage. Currently he is home with a catheter and he is leaking, but I've noticed a few drops of blood. Is this norma
I am sorry to hear about Dexter. You don't mention if this is a urinary catheter or an intravenous catheter. We will sometimes see blood in the urine come out of a urinary catheter in cats with a UTI or cystitis, so it is not unusual but definitely something to let your vet know about. If this is an intravenous (IV) catheter in a vein then we would be concerned it is coming out or the cap is detaching and leaking and it may need to be removed and he should be seen by the vet as soon as possible.
