I bought an inexpensive stethoscope at a nursing uniform supply company.
They are also available online or at medical school bookstores.
I counted for 15-30 seconds and multiplied by 4 or 2
depending on how tolerant the cat was. 140-160 is pretty easy to count.
Over 200 was much harder to count and I left it at over 200.
I liked listening to the heart because I could note changes in the
heart rhythm. I noticed an extra sound at one point. I didn't know
what it was, but noted the change for the vet/cardiologist.
