Why is my spayed cat peeing white pus and having brown discharge?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed

my cat had white pus like liquid in her urine. This is the second time this has happened. Also, after every few weeks brownish liquid comes out of her vagina even when she has been spayed.

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!
