Cat-Thematical Games

Never heard of Cathematics ? It's a in-house mix of two passions: cats and logical/mathematical games !

I intend to post, roughly once per month, a new enigma. Some will be easy ones (*), some will require a little more thinking (**), and others will be quite hard (***). Previous puzzles remain on line (see menu at left to access them).

If you really feel stuck, click on the link under the puzzle to give me the e-mail address where I can send you a pdf file with the commented answer...
