The mark consists of the word "Hartz" within a shaded rectangle with rounded corners overlapping a single line circle. Inside the single line circle is another concentric, single line circle. Between the two single line circles, at the top of the mark, is the arched wording "CAT TOYS" and between the two single line circles at the bottom of the mark is the arched wording "EVERY TOY FILLS A NEED". The word "INTERACT" appears horizontally overlapping the outer single line circle on the left side of the mark and the word "SWAT" appears horizontally overlapping the outer single line circle at the right side of the mark. Inside the inner single line circle are three smaller, overlapping single line circles. The upper left overlapping single line circle is overlapped by a human hand dangling an object over a cat on its hind legs. The upper right overlapping single line circle has within it and overlapping it a cat following a ball, and the lower overlapping single line circle has a cat following a mouse above the word "HUNT".
