Dave, you can buy shower perches with the suction cups, but I highly recommend spending the extra money and buying the ones that have a square plastic cover over the suction cups. Talon has chewed the suction cups and has pulled them off the wall. I have gone through 4 of them before finding the one with the covers on them. She still occasionally manages to get it to fall off the window. (I use them on the windows, as she HATES getting wet in the shower. I have them all over my house windows. Spoiled little thing that she is!!) :pinch:
