A. You didn't specify her age, but you did call her a "kitten", so I'm going to assume she's very young. Sneezing and coughing are signs of upper respiratory disease, which is very common in immature immune systems. Typically they're viral in origin, so we just make sure they have good nutrition (feed canned food, slightly warmed in the microwave to stimulate appetite when their noses are stuffed) and provide humidification to the environment with a humidifier or by putting them in the bathroom when you shower. If green or yellow nasal nose or eye discharge appears, or if she stops eating, it's time to see the vet.
