Why does my kitten suddenly have watery eyes, sneezing, and diarrhea?
Jack's eyes and stool most likely are not related although can be.
He may have an upper respiratory infection, conjunctivitis (inflammation in the conjunctiva of the eyes which may be infection vs allergic), Jack can have a corneal ulcer (less likely if it is both eyes that are affected) or even allergies (which are less likely due to age).
With all of his symptoms, including a runny nose and sneezing it seems more like an upper respiratory infection. It is a good sign that he is still full of energy.
With his stool, it can be stress or intestinal parasites. It can also be that he got into something he wasn't supposed to or even a virus. When you go to the veterinarian I would recommend bringing a stool sample so the veterinarian can make sure there are no intestinal parasites.
They may dispense eye medication and medication to help with the diarrhea. Depending on the cause they find it just may be antibiotics for the diarrhea or it may be a dewormer. They also may dispense a bland diet for Jack.
I hope Jack feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach.
