Just like a human's should be. Fraser is sitting beside me, his front half draped over my leg. I noticed that I could feel what seems to be his heartbeat on my leg and it's going beat beat, beatbeatbeat-- little clusters of beat in between regular ones. I put my fingers on his ribs to feel it better and it just doesn't seem regular. Maybe there's something about the angle and I'm not picking up all the beats. Thoughts? Should I take him down to the vets? Otherwise, he seems normal--food, energy, pooping, water etc.
