Merck & co., inc., kenilworth, nj, usa (known as msd outside of the us and canada) is a global healthcare leader working to help the world be well.

The decreased volume of blood pumped out of the heart can cause the paws and ears to feel cold and can lower a cat's body temperature. Heart rate variability is used primarily in research, but evidence suggests that it provides useful information about left ventricular dysfunction after myocardial infarction, heart failure, and hypertrophic cardiomyopathy. A domestic cat's normal heart rate ranges from 140 to 220 beats per minute (bpm), and is largely dependent on how excited the cat is. A normal cat's resting heart rate is 120 to 140 beats per minute.
