We introduce quasiprobabilities based on the so-called squeezed states to represent the density operator of an oscillator. Such representations become especially useful for oscillators designed to display, strong excitation notwith-standing, pronounced quantum features such as squeezing of the quantum fluctuations of certain observables below the limit characteristic of coherent states.
