Limp on a Limb

Sleep...the purrfurred portion of the feline day (cats both domestic and wild). With nary a tense muscle or twitch-- the calico housecat, tiger, jaguar, cheetah, leopard, puma, bobcat, lynx, ocelot and a few other cats that have escaped my mind--display a sense of safety amid their surroundings, saving energy while in purrfect repose.
