I *saw* Floofy's pulse!
Everyone knows how to check their sleeping cats for breathing by watching their abdomen/ribs rise and fall...but I saw something interesting, last night!
Our computer desk has a hole cut in the top for the wires to come out to the desktop and it also lets heat out and warms the wood of the desk, so that is a PRIME napping spot. Last night, Flooter woke up and I could see the fur of his neck *pulsing* with his heartbeat! I checked and he wasn't purring, he was just breathing normally, but both sides of his neck had the 'pulsing' fur. It was very neat! I had just thought to time/count it and another cat made a noise in the other room that he had to jump up and investigate so I didn't get to take any notes...but I will be watching for that to happen again.
