Cat At A Loss For Words (And Rawrs, And Mews, And… )

What changes a cat’s voice? The answer has a lot of factors.

I have a question that several veterinarians could not answer for me. My cat Sylvester seems to have lost his voice. What would be the cause of this? Could an illness be involved?


Loss or change of voice is one of those vague problems that drive vets crazy.  In most cases that I’ve encountered, I could not attribute the voice change to any particular cause.  In some instances, however, the cause is readily apparent.

  • The most common cause I’ve seen is a viral upper respiratory infection, with the herpes virus and/or the feline calicivirus being the main culprit. Most viral upper respiratory infections result in runny eyes, snotty nose and lots of sneezing. Occasionally they’re result in laryngitis — a “sore throat” — and a hoarse or lost voice.
  • I’ve seen cats with oral tumors involving the throat or the vocal cords that resulted in a voice change or loss. Finally, there is a condition called laryngeal paralysis, in which the nerve that controls the vocal folds becomes damaged, causing the larynx not to open properly, resulting in a change of voice. This is much more common in dogs than cats. Interestingly, I diagnosed my first case of this about four days ago.

Even though most cases are due to upper respiratory infections, which are fairly benign, a change in voice should be evaluated by your veterinarian. He or she might want to sedate the cat and perform a thorough oral exam, looking at the back of the throat, and even trying to pass an endotracheal tube down the trachea to see if there is a mass or other obstruction. X-rays may be necessary to look for masses that are in the trachea or in the neck that cannot be detected simply by feel.
