Why is my cat peeing blood after a being neutered/spayed? (Female) She was not doing this before the operation. Vet seemed unprofessional.

There is a chance that there was some trauma to the bladder area while removing the uterus which is located just above the cervix. Some light bleeding can be expected to occur for 1-3 days after surgery but copious amounts of blood or prolonged bleeding should be considered abnormal. I would recommend either taking your cat back to the previous veterinarian, since he/she did the surgery, for a follow-up visit for further care. Or if the trust has been broken with this vet, you can get kitty seen with another expert for an exam and potential urinalysis to ensure there isn't a UTI present that could explain the symptoms that mentioned. As long as there is an active flow of urine and no outward signs of illness (vomiting, diarrhea, bloated abdomen) then this sounds like a relatively non-emergency type situation that can be hopefully be resolved with medical treatment, if any.

It could be due to the surgery or due to pain and stress (which can lead to bladder inflammation and bloody urine). if you do not trust this vet, take her to a different vet tomorrow, it sounds like she needs to be seen ASAP.

Not knowing when exactly your kitty was spayed makes it impossible to tell you why she is peeing blood. There are two possibilities: 1) she could have a urinary tract infection 2) she could have a stress-induced idiopathic urinary tract infection and 3) there is a possibility that there is some residual bleeding from the spay from the point where the uterus was ligated. This would only happen maybe the first or second day after the spay. In any case I would go back to the vet for a recheck, or, if you are not comfortable with your vet, get a 2nd opinion at another veterinarian.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. 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!

Oh no, poor Nova! She could be peeing blood because she has a UTI or bladder stones. She will need to see a vet for this as soon as possible. If she appears otherwise healthy and happy, eats and drinks plenty, you can wait until tomorrow morning. If she appears lethargic, ill or distressed, or if the urine appears very bloody, then she should be seen by a vet ASAP. Feed her wet/canned food, add water to it, and make sure she drinks a lot of water to help flush the bladder.
