Some of the best pitches are products that "appeal to the masses," Andrew Figgins, a Chicago-based entrepreneur and owner of the fan site InTheSharkTank.com, recently told Business Insider.
The following "Shark Tank"-approved items (all were picked up by Sharks on the show) are certainly appealing, and would make fantastic gifts for the "Shark Tank" fan in your life.

Each successive tray has less litter in it, and over time, the litter -- and tray -- disappear altogether. At the end of the training, the cat is able to use the toilet without help.
