My kitten has diarrhea since yesterday, refuses to eat and drink and vomited just now. He has sarcoptosis and has had 3 shots of ivermectin. Could he have taken too much of medicine? or what else could have caused this? Thanks

Poor Bugsy! Ivermectin would not cause these symptoms, so I doubt that this has anything to do with his medication dosage. In a kitten this age, I would be concerned that he may have feline distemper (panleukopenia) if he is not current on his vaccinations. He may also have a severe case of intestinal parasites, or he may have ingested something toxic. I would recommend taking him to the vet today for an exam - vomiting and diarrhea in a kitten that is not eating are always very concerning, since he will become dangerously dehydrated quickly without treatment. Your vet can start IV fluids and supportive care if needed, and can also do a fecal exam and blood work to help determine what is causing these symptoms.
