  We present the generation of approximated coherent state superpositions -
referred to as Schr\"odinger cat states - by the process of subtracting single
photons from picosecond pulsed squeezed states of light at 830 nm. The squeezed
vacuum states are produced by spontaneous parametric down-conversion (SPDC) in
a periodically poled KTiOPO4 crystal while the single photons are
probabilistically subtracted using a beamsplitter and a single photon detector.
The resulting states are fully characterized with time-resolved homodyne
quantum state tomography. Varying the pump power of the SPDC, we generated
different states which exhibit non-Gaussian behavior.
