I have a 14 week old kitten who has had diarrhea for over 3 weeks now. She has been on every possible antibiotic and is now on Ronidazole. She has been on it for 3 days and is still experiencing fecal "leaking" and severe diarrrhea. For those who have had cats on this drug before, how long does it take for the drug to kick in and see the diarrhea decrease/go away?? IS there any chance it could actually be making the diarrhea worse? Thank you for your help, I am so desperate for answers!!
