not too differently from normal animals, to be honest! there Are small differences between normal animal feet and the mammalian egos’ paws/feet, examples being:
the large part of Wilf’s paw pads don’t have that little divot in the middle, meaning that he leaves heart-shaped pawprints
similar to Wilf, Yan’s paw pads don’t have the little divot, meaning she leaves heart-shaped pawprints, too
Ed’s hooves always the four lines on the main hoof/nail, mimicking the lines on a dog’s paw
if anything, the main difference lies in when they shift to their human form [example below]. their hands are mostly human, save for the pads of their fingers retaining their paw pad color depending on how much they shift.
(for the catlike folk, their fingers become thicker and their nails can sit inside the muscle like a cat’s nails, but we’re talkin’ paws rn, not nails dnifdjs)
