I had gotten a Hello Kitty bathroom rug that is just the cat face and it doesn't have the rubber backing, but it doesn't move around. Except when Shelby the cat runs at 100 miles per hour with her catnip goldfish "Goldie" in her mouth, jumps onto the Hello Kitty Rug, sits on it and "rides it" across the bathroom floor bumping it into the shower. She further developed a rug surfing style on the Hello Kitty rug and dropped "Goldie" on the rug to "meow, meow, meow" while surfing the rug across the bathroom floor. Her brother never did any of this. Shelby's brother and I will be asleep at 3:00 in the morning and wake up to Shelby and Goldie running around my place with the joyous "meow, meow, meow." Her brother puts his head up in bed next to me and looks at me and I tell him "hey, she's your sister, you go tell her shut up" but we both put our heads down to try to get sleep. Finally, I had to put Goldie away at night so her brother and I could get our sleep. Cat rug surfing has totally stopped at all times of day and I have ruined the cat fun. Apparently all the shennigans weren't the fault of Shelby the cat at all, but the total fault of Goldie the catnip goldfish. Maybe Goldie has a bit of Clown Fish in her.
