Cat got diarrhea after neutering

I read all the previous posts with the same question so I understand it might have been caused by the anesthesia. But it been a week since the surgery and my kitty is still having diarrhea. The medicine, antibiotics and probiotics helped for like 2-3 days then the diarrhea comes back. Is this normal?? Someone please tell me if you had the same experience. Would help a lot. Thank you!!

This is just venting: I’m so stressed bc of this. His soft 💩 got everywhere, on the floor, on my bed all the time. No amount of cleaning helps. This gonna drive me crazy 😭😭😭
