Well, they are family, so I am parenting them...
I have 2 Devon Rex's that I adopted (2 females), they are Mother and Daughter and we were co-existing nicely....until....they started peeing EVERYWHERE!!!!
I mean nothing is sacred, they've peed on my ironing board (wtf?), down the front of my wardrove mirror, the kitchen table

and countless other places. They did pee on the phone bill, but the dude I spoke to on the phone didnt find that a suitable reason for not paying my bill on time.
They have clean kitty litter and have been here for 5-6 weeks....any ideas??? Its driving me friggen spare!!!
