My one year old kitty breathes extreme fast. Even at rest his breath rate averages between 80-120 bpm. The only time it is in the normal range is when he is asleep. He doesn’t seem affected by his tachypnea, he is active and normal as to be expected. I’m curious to know if anyone has ever experienced this before. (He has been this way since birth, been to a vet and had an X-ray which they said was normal). None of my other cats are like this except for his 2 sisters and their mother which are the same way but not as fast as him. I’ve went down many “rabbit holes” trying to find some answers with no luck. All the possible causes of consistent, long term tachypnea he doesn’t have (per his vet). But every time I see him breathing it drives me nuts. Not only is his chest rising/falling but so does his lower abdomen on the sides. Any thoughts?
