As you know, they pee to mark their 'spots'..and as you have seen, they
do it often. Try a strong cleaner to remove all traces of the scent -
and give them a pee-place to 'call their own' to take their minds off
that spot. I've read that if you take some of the material that they
will pee on regularly and put it in the place you want them to pee in,
they tend to start using that spot.
In the meantime, try this- (not sure if it will work)
clean the area near that spot well...and move their food/water there.
They may be less likely to projectile pee in that spot for obvious reasons.
On another note, I plan on using the term 'projectile pee' in the near future.
Haven't seen your setup, but gimmie 10 minutes, a pocket knife, & some
gum and I can prolly rig something.
The gum is for me to chew on.
