Help stopping bed wetting?

[katsdad]

Our cats (4 of them) have their own room we keep them in at night.
In the room there is a bed that they usually sleep on. We are having
a problem with one of the cats (we assume it's just one of them)
urinating on the blankets that are on the bed. We have 2 litter boxes
in the room that we clean twice a day, so its not that they don't have
a place to go available to them.

We keep the mattress covered in plastic and remove the blanket or
sheet as soon as we've discovered it wet.

It doesn't happen every day, but often enough to be real nusance.

Any suggestions?

First of all I would get them checked by the vet.

You might also try adding more litter boxes, the general rule is one box per cat plus one.
