Indica may have a hairball she is trying to get rid of, so generally it is a good idea to regularly feed hairball remedy or a cat food with hairball remedy, especially if your kitty lives indoors only. Of course there may be another cause for this, such as an upper respiratory disease, a gastric problem, or a foreign body stuck in the trachea or esophagus or laryngitis. As you can see there are many possible causes, and you are doing the right thing by taking her to your veterinarian today.
