,and at the grand old age of two hes just started spraying
hi pantsonfire,
As i put in my thread both my neutered male cats have sprayed and both were neutered young and it still smells just as bad

, I've found it only happens when they are stressed by something (such as a cat trying to break in - see thread!

). For cleaning I put non bio washing machine powder with water because it neutralises the ammonia from the spray. If your cat doesn't go out and you can figure out what's caused him to start spraying then you may not need to get him neutered.
