Is the head on the right or on the left? It helps to know which direction the cat is laying. Which pink area? The one closest to your thumb or the one on the far right that looks like it has a tiny red scab in the middle? The one near your thumb is likely a nipple. Male cats do have nipples hiding under all that fur
I'm not sure what the other one could be. Maybe you can send your vet an email with the picture and ask.
