Why is my cat still discharging pus after stump pyometra surgery?
Hi Maleeka! I'm sorry to hear that Mira has had these ongoing issues. It is uncommon to have a recurrent stump pyometra. At this point, other issues should be considered, such as an ovarian remnant syndrome (a portion of an ovary remained after a spay or was present in an abnormal location), contact with any human hormone creams/ointments, or resistance to the antibiotics being used. A 5 day course of amoxicillin is not likely to treat this type of issue. At this point, I strongly recommend taking Mira back to her vet for further evaluation, including a physical exam, blood testing (primarily to check her white blood cells), and possibly another surgery. She may need to have biopsy and culture samples taken of the uterine stump. I hope this helps and that all goes well!
