Hunter was recently diagnosed with restrictive cardiomyopathy (a heart condition that led to fluid accumulating in his heart and lungs).
We were instructed to monitor his condition by measuring his breathing rate regularly. To do this, we should count the number of breaths (an inhalation and exhalation) that he takes in a minute. We were instructed to do this when he is relaxed or asleep.
When he's relaxed he's usually purring. Does purring affect his breathing rate? Should we only measure his breathing rate when he's not purring?
