Cats are wonderful creatures but you better not put them together without proper introduction. So, plan ahead to display them in the right order so they get along! When you adopt a cat and there is(are) other(s) cat(s) already living in the house, you need to make a gradual introduction first. Sudocats can be handy in that matter! • Relaxing experience • Classic sudoku with cats • 4x4, 6x6 and 9x9 puzzles • Customizable grid/background • You can change cats/numbers anytime
