Modern Living Fixable bowl Denver, silver

I bought this tray because it was supposed to stick to the smooth floor. But it doesn't work at all, and the little tab on the ring that's meant to help you lift it off the floor is completely useless. Really disappointing!

I bought these two bowls because my cat always manages to drag around any anti-slip bowl, even the ceramic ones! With water all over the house every day, I finally decided to try these. But unfortunately, the suction cup is so weak that it’s useless. Tried it on porcelain tiles and even on glass stairs. No luck.
