Abstract: A transformable balance board that may be alternately used as a balance board or wobble platform and a wheeled board or roller platform. The balance board includes a rigid platform preferably covered with a closed-cell yielding foam pad layer on top on which a user can support his or her weight. When used as a wobble platform, a relatively large central fulcrum member extends down from the rigid platform so that the board wobbles with no stable horizontal position. In a second usage configuration as a wheeled board or roller platform a plurality of sturdy wheels or rollers retracted into the underside of the rigid platform are extended vertically downward from their retracted positions. Because the vertical height of the wheels is greater than the vertical height of the fulcrum member below the rigid platform, the wheels make contact with the ground and the fulcrum is lifted up and out of contact with the floor below.

Abstract: A tidy pet litter box having a plurality of internal screens across which the pet must traverse when entering or leaving a main basin of the litter box. An upper lid fits over a lower tray, the upper lid having a large front opening. The lower tray defines a large main basin in which litter is placed, and a secondary basin at a rear end thereof. An entrance screen mounted laterally across side walls of the upper lid extends from a lower end of the front opening substantially over the entire main basin and permits passage of a pet to a rear screen located above the secondary basin. To exit, the pet must jump up to the rear screen, then over the entrance screen which dislodges any litter sticking to its paws so that it falls back into the main basin. A method of training a cat to use the litter box by first removing the entrance screen is also disclosed.
