I have two litter trays - one for upstairs and one for down. The upstairs one I keep by the bathroom. Last week I'd noticed male had done his business in the bath. I didn't really say much as I noticed the tray wasn't in the usual place (I think one of the kids moved it).
But yesterday I'd noticed he'd gone in the bath again and his nice fresh tray was where it was supposed to be. I know it was male too as girl was outside.
Anyone else had this issue? I've taken to completely keeping the bathroom out of bounds. Something he's quite annoyed with as for some reason he enjoyed sitting on the sink.
