                  Domestic cat




                                Walking through any wild place, we
                                are aware of many animals. Birds fly above,
                                insects buzz from one flower to another, and
                                fish rise to snatch food from the water’s surface.
                                But where are all the mammals? With their swift and active
                                habits and their keen senses (p. 16) they make themselves scarce,
                                fearing the large creature blundering past. Others, being nocturnal, are
                                well hidden and asleep. Although we are mammals ourselves, we seldom
                                have the time and patience to glimpse our wild relatives. Often, we only
                                know of their presence from the tracks and signs they leave behind;
                                footprints and belly- or tail-drags in the ground, leftover bits of food with
                                teeth marks, droppings, burrow entrances with dug-out soil, bits of hair
                                caught on twigs and snagged on thorns, and castoffs such as antlers (p. 62).
                                The footprints shown here are actual size, and actual prints made by
                    Front print  the walkers themselves: real and messy,
                                not cleaned and tidied up. The prints were
                                made by encouraging the animals (by
                                bribing with food) to walk on a pad of
         Toe pad                nontoxic ink and then across the paper.
                                Claw marks do not show up using this
                                technique, but they will be found in trails in
          Intermediate pad
                                soft mud or snow. In a trail, the spacing of
         Hind print             the prints and the depths of their impres-
                                sions allows us to work out whether the
                                animal was running or walking.

                                                    When sitting or hopping slowly, the
        DIGITIGRADE KITTY               Front print  rabbit’s hind foot leaves its character-   CLOVEN HOOVES
        The domestic cat is digitigrade (a toe-     istic long imprint compared to the   Animals that like mud provide plenty of prints

        separated from the main three-lobed         running the difference is less obvious,   the better. A half-ton wallowing buffalo left
        sole, or intermediate pad. There are        since the animal tends to place only   this clear cloven-hoofed print (divided in two),
        no claw marks: the claws are kept           the tips of its hind feet on the ground.  indicating it is an artiodactyl or even-toed
        sharp in their sheaths until needed.                                       hoofed mammal (p. 10).
        Neither is there a mark from the
        innermost (1st) toe on each front foot,           Hind print
        which is too high to leave a mark.                              Feet are
        Hence both front and hind prints are                            covered with fur ­
        four-toed and roughly the same.                                 no pads show
