My cat is peeing blood after spay surgery. Is this normal or serious?
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.
