How much is he peeing? If he has never done this and just recently started he could have a urinary tract infection. Males do mark, but it's little drops to mark you like the others said, however if he is peeing a lot I would take him to the vet for a checkup. Or you could just be having him out for too long, without giving him a potty break so he is forced to go to the bathroom on you.


If you don't like it, as soon as he pees on you put him back in the cage ASAP, this way he will know that peeing on you means he will no longer get out time, and that he must hold it longer or let you know when he has to go. Try putting him back in the cage every 20 minutes or so to allow him to go to the bathroom. Chances are you are having him out for too long without allowing him a potty break.

It's this that is scaring me...."but lately he's been peeing whenever he is taken out, this just started about a week ago". So this very well could mean something.

Just curious but why do you only have one rat? Rats are very social and really do better in same sex pairs so they can have attention from their own kind.
