As your cat is spayed, it is possible that the discharge you are seeing is coming from the urethra rather than the vagina as both open up into a common vestibule in the body. Dark brown secretions may indicate blood or infection in the urine, and bringing in a sample of your cat's urine to your local vet can be used to determine if this is the case. You may see other signs of illness such as more frequent trips to the bathroom, attempting to go without success, yowling, or pain and irritation. Infections are usually treated with a round of antibiotics as well as switching to a urinary friendly diet. Increasing your cats water consumption will also help reduce further infections. In some very rare cases, part of the uterus can be left behind during a spay which may become infected. Signs of infection include swelling of the abdomen, extreme pain and lethargy, and greenish or yellow discharge in addition to other possible discharge. This is a serious condition which should be seen by a veterinarian immediately.

    Hello, and thank you for your question. I worry the white substance in her urine may reflect an infection in her vagina or bladder. Did you confirm the brownish liquid is coming from her vulva, and not her bum? The anus is right below her tail, while the vulva is much lower on her back end. If the brownish liquid was from her anus, then it is diarrhea. In either case, these problems should be assessed in person at a vet, as ongoing diarrhea can cause dehydration and discomfort. The vet may request a fecal test and a urine test to check the underlying problem. I hope this helps, and that Shuka is feeling better soon!
