Hello my cat experts. About 2 months ago I adopted a stray that showed up in the driveway SEVERELY ematiated. She's been to the vet before being introduced to the household, all tests for FIV, etc. came back negative, was dewormed and she did get her shots. I thought the diarrhea would pass in a few weeks with a good diet but she is still having daily diarrhea, sometimes the consistency of pudding. She will also vomit when she overeats (I guess she remembers being without). I have started giving her SEB once a day and a probiotic. Any other suggestions? I have 6 cats and if I can resolve this without a vet trip, my wallet would thank me. I do have Metrodozonale available. Any suggestions appreciated.
