Technically, choking is when something lodges in the larynx or trachea, preventing air flow. This can be nearly anything, even a small object such as a pen cap, bell, or thimble. Fortunately, choking is a rare occurrence in cats.
Pieces of cat toys like small pompons or bells, splintered bits of bone, and other foreign objects can potentially get stuck in the larynx and cause choking.
If your cat is conscious and not too upset, you can try looking in his mouth for any foreign object. Remove it if you can, but in most cases you will probably not be able to do so safely. However, if your cat is too upset for safe handling, wrap him in a towel or put him in a carrier for transport to the veterinarian.
If your cat is unconscious and not breathing, or breathing with great difficulty, do the following:
A note about strings: If you find a string (thread, tinsel, etc.) in your cat’s mouth, the temptation is to pull it out. Unless it slides out like a wet spaghetti noodle, DO NOT pull it. It is likely stuck somewhere inside and pulling will only make things a lot worse.
Diagnosis will be based on examination of your cat and your description of what happened. X-rays of the head, neck, and chest may be necessary to locate the foreign object. Sedation may be required for the examination and X-rays.
Your cat will most likely be sedated or anesthetized in order to remove the foreign object. The removal may be as simple as pulling it out of the mouth, or it may require a complicated surgery on the neck. The foreign object may cause damage that may require suturing or antibiotics, especially if the object has been lodged for a while.
Once the foreign object has been removed, healing usually proceeds without a problem. If there was severe damage from the object, or if surgery was required, laryngeal paralysis is a possible complication. Scarring could cause strictures (narrowing of a passageway) to form, which could make breathing or swallowing difficult.
If your cat was without oxygen for an extended period of time, that could also cause problems, usually of a neurologic nature, such as blindness or mental dullness.
Just as with small children, you need to be aware of potential choking hazards in your cat’s environment. In addition, something labeled as a cat toy is not necessarily safe for your cat, especially after your cat has chewed on it extensively.
