My quaker is approximately 23-24 years old. Ive noticed the aging taking its toll over the last year or so when it comes to general liveliness and overall behavior. I do everything I can to make him comfortable. Lately Ive noticed he makes a squeaking noise or perhaps he is wheezing. Sometimes It sounds like its in tune with his breathing but other times its random and different tones/pitches.. It happens quite often when he is eating but it certainly does not slow him down while he is eating.
