Okay so i have a few males indoors. I have noticed consistently pee up the radiator next to there enclosures- neutered males!!. This not being so with females. Anyone else get this problem indoors and what do you do to prevent it or do you just live with it and clean it off? Only thing is it's also going to go up the wallpaper if i don't watch it and that will be a mission to sort. They binky and pee upwards, the girls don't obviously which in my mind makes them cleaner and easier to live with than male buns. Anyone else find this?
