My four year old tom is neutered (was done at about 5/6 months iirc) and is pretty clean around the house. However, yesterday he was very restless - I blamed the terrible weather which means the cats have been more or less housebound for weeks - and racing round the living room, upending plants and knocking things over. Then he suddenly sprayed a jet of stuff from his rear end all over the TV unit! I am baffled as I thought neutering was meant to stop this behaviour in toms? No damage done and there isn't a bad smell from it, thank God - we had an intact tom when I was young and I remember well the horrible stench if he sprayed indoors, but is this a still a thing in neutered cats that I'm just not aware of?
