Thanks for using Petco Pet Education Center, formerly Petcoach! Possibilities to explain this finding include a urinary tract infection, urinary tract stones, inflammation of the urinary tract, among others. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. If at any point you notice that he is unable to urinate, have him evaluated as soon as possible as that may represent a medical emergency. Good luck!

    Thanks for using Petco Pet Education Center, formerly Petcoach! There are daily variations in urination. If he is able to urinate, I would not be too concerned about this at this point. However, if he starts having issues urinating such as not being able to urinate or urinating in small amounts frequently or urinating blood, have him evaluated by a veterinarian for further assessment and treatment. Good luck!

    Good morning. Thank you for using Petco Pet Education Center, formerly Petcoach. Blood in the urine in a male cat can be from many things but the most common things would be stress cystitis (inflammation of the bladder), bladder stones or urinary crystals. This can be a serious problem. I suggest you take him to your vet for an exam and to have his urine tested.

    Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Dexter. It could be he is suffering from feline idiopathic cystitis or bladder stones causing this urination behavior. If he appears otherwise healthy and happy, eats and drinks plenty, you can wait until tomorrow morning to see a vet. If he appears lethargic, ill or distressed, he cries when urinating, tries to urinate but nothing comes out, he makes multiple trips to the litter box, or if the urine appears very bloody, then he should be seen by a vet ASAP. Feed him wet/canned food, add water to it, and make sure he drinks a lot of water to help flush the bladder. I hope this helps!

My cat is peeing blood, I think it may be because a uti not for sure just very worried
Thanks for using Boop by Petco! This could certainly be a UTI. Other possibilities include urinary tract stones, feline lower urinary tract disease, among other possibilities. I recommend that you have Simba evaluated by your veterinarian for further assessment and possible treatment. Further diagnostics include a urinalysis, urine culture and some form of abdominal imaging such as abdominal ultrasound. Treatment would be based on findings. Good luck and have a good night!

My (around 2-3 year old) female cat is peeing blood, often but in very small amounts, is both outside and inside the litter box, and takes a VERY long time to pee. She is eating, drinking, and playing normally. Do you know what might be happening or
Hello and thank you for contacting Boop by Petco. Mamacat most likely has cystitis. It is usually related to bacterial infection of the bladder but it may be due to bladder crystals or stress. Please, take her to your local vets for an appointment, as most likely she will need a course of antibiotics to get better.

My cat is 3 years old and has been experiencing blood in urine since two weeks ago and drinks more water. Her SDMA is 21 μg/dL, which seems to be a rather high level. The vet we went to said that she had mild renal failure but stopped short of giving
Thank you for submitting your question regarding Kiki. I recommend that she has a urine culture to see if she has a urinary tract infection. If so, it can spread to the kidneys causing damage resulting in an elevated SDMA. She will also need x-rays of her abdomen to check for bladder stones. If these tests are negative, idiopathic cystitis is common in cats. It is inflammation in the bladder that can lead to blood in the urine. If her veterinarian is concerned with kidney disease, then her blood pressure should be measured. Diet recommendations will be based on her final diagnosis. I hope this information helps!

My 2yo female cat had blood in her urine last Friday. We took her to the vet right away fearing it's urinary track infection. The test result came back today and the diagnostics is she has urinary track inflammation, not bacterial infection. We've be
Hi there! Thanks for using Boop by Petco! There are a few things that can cause this type of symptoms in cats. Generally, in a female cat, other things to rule out are urinary tract stones and even tumors. The next diagnostic step would be an abdominal ultrasound. If unable to proceed with this. At the very least, abdominal radiographs (if ultrasound is not available) could help rule out most of the types of stones. I recommend that you let your veterinarian know that she has not improved so that further diagnostics and treatments can be pursued. If no cause is found and is truly suspected to be feline lower urinary tract disease, your veterinarian may add a medication called Prazosin which can help pass urine. If you ever notice that she is not able to pass urine at all, have her evaluated right away. Good luck and have a good evening!

My male cat has started weeing blood and going to the toilet more often . He seems okay in himself still eating and drinking .
Poor guy. He likely has a urinary tract infection or cystitis (inflamed bladder usually due to stress). I would recommend taking him to your vet for a urine test to determine which is present so that he is treated appropriately. As long as he is otherwise acting normal and able to urinate at will, then it isn't considered an emergency at this point. Getting him seen on Monday or the day after should be ok. It is likely he will be prescribed antibiotics and/or a prescription diet to treat this successfully. I hope that Milo gets better soon. Best wishes and take care.

Minx is not using the cat box, refusing to eat, crying and now there is spots on blood on the floor. Help
Hello and thank you for reaching out to Boop by Petco. Given that Minx is a young male cat and having abnormal urinations and likely blood in his urine, I suspect that he may be suffering from Feline Idiopathic Cystitis (FIC), or inflammation in the lower urinary tract. This is causing him difficulty urinating, and painful urination. I recommend having him seen by a veterinarian right away, before he becomes fully "blocked", meaning unable to pass any urine at all. This is a life-threatening emergency, and requires rapid veterinary attention. Your veterinarian will perform a physical exam and likely recommend bloodwork to evaluate the severity of his urinary tract disease. FIC is a treatable condition, but again, if he becomes unable to pass any urine at all, he can experience acute kidney failure and develop fatal heart rhythms. I hope this is helpful!

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!

Hello. I took my cat to the vets because she had blood in her urine. They gave me metacam to give once daily. She peed outside the litter box and there is more blood than before. Please help
Thanks for using Boop by Petco! She should be re-evaluated at this point. The urinary tract symptoms you describe could be due to a urinary tract infection, urinary stones, a tumor, among other possibilities. I recommend that you have Sophie re-evaluated by your veterinarian for further assessment and treatment. Further diagnostics would include abdominal imaging and lab work. Treatment would be based on findings. Good luck and have a great day!

my cat is peeing blood and not eating anything
Hi, thanks for using Boop by Petco! Poor Julie! Blood in the urine can indicate a urinary tract infection, crystals in the urine or bladder stones. She may not be eating because she is uncomfortable or has a fever. I recommend that Julie sees a Veterinarian. They may check her urine for infection or crystals. If she is older they may want to run blood work. They also may want to take an X-ray to check for a bladder stone. If it is a urinary tract infection she needs antibiotics. If it is crystals in the urine then we usually change the diet. If bladder stones, ideally surgery is recommended. I hope this helps and I wish Julie a speedy recovery!
