Pet's info: Cat | Mixed Breed | Male | neutered | 9 lbs
My neutered 10yo cat has been licking his penis lately. When he’s doing this, it’s fully out/erect (I think) and red. He’s been doing it for about several months. Tonight I caught him doing it again and googled the behavior, finding that male feline urinary blockages can kill in a matter of hours. Im panicking that I will wake up in the morning and my boy will be dead. He is not lethargic and his belly is soft. He seems normal and is jumping and running. Should I be immediately concerned?

He is most likely experiencing pain from urinary crystals. Very common in male cats. This can become a very big problem as often times the crystals will form together into a "glob" and get stuck in the urethra causing an obstruction which is an EMERGENCY! They can also form stones in the bladder. So, you really need to get him to your vet for an examination and urine test.
