text_A: Hyenas groom themselves often like felids and viverrids, and their way of licking their genitals is very cat-like (sitting on the lower back, legs spread with one leg pointing vertically upward). However, unlike other feliforms, they do not "wash" their faces. They defecate in the same manner as other Carnivora, though they never raise their legs as canids do when urinating, as urination serves no territorial function for them. Instead, hyenas mark their territories using their anal glands, a trait found also in viverrids and mustelids, but not canids and felids. When attacked by lions or dogs, striped and brown hyenas will feign death, though the spotted hyena will defend itself ferociously. The spotted hyena is very vocal, producing a number of different sounds consisting of whoops, grunts, groans, lows, giggles, yells, growls, laughs and whines. The striped hyena is comparatively silent, its vocalisations being limited to a chattering laugh and howling.
text_B: If you were to see a cackle of hyenas in the wild, who had just feasted upon prey and thus had blood around their mouths and muzzles, would you expect this to be wiped away soon after the animals settled down?
NO.
