We have a new little kitten, he's four months old on the weekend & he keeps weeing everywhere. He has a little tray that he uses about 90% of the time but sometimes he'll just wee anywhere. He's done it on Juliette's little fold out lounge & then this morning when I was dropping Zander at preschool he has gone on the beanbag.

Any ideas why he would be doing it only sometimes & how to stop it?

TIA
