I adopted an 8 week old kitten from a vet's office yesterday. She's been tested for all the common feline ailments, her stool was checked, and she is completely healthy. She was given her first set of vaccinations and was treated with flea medicine. The vet told me when I picked her up yesterday that she started having mild diarrhea on Wednesday (yesterday was Friday) and she's currently on .4 ml metronidazole twice per day. The vet said it's more than likely an intestinal parasite. Does anyone know how long diarrhea usually lasts in kittens? We haven't switched her food. Thanks!
