Scrawny means unhealthily thin and bony. A scrawny cat, scrawny arms, looking scrawny.
It is unkind: slim is a compliment, thin is neutral, and scrawny suggests undernourishment and a certain awkwardness. It suits animals, chickens and adolescents. Skinny is the milder everyday word and scraggy the near-synonym. Note that scrawny is chiefly American in origin and now general; and that it is a variant of dialect scranny, from a family of words about being meagre.
