I have a ragdoll kitten (13 weeks old) that developed loose stool about a week and a half after bringing him home. He also started sneezing and has one eye that tears a lot (all started several days after bringing him home). He seems in good health otherwise (e.g., lots of energy and eating/drinking fine). We had another ragdoll kitten that had the same issues. After going through various trials of medication and trying bland food the breeder allowed us to return the kitten and get a new one. After several days with the breeder that kitten no longer had loose stool. We thought it was something specific to that kitten. However, the same pattern is now emerging with the new kitten. The vet doesn't seem to know what could be going on. Does anyone have any ideas or advice?
