  We analyze the properties of a non-Abelian spin-1 chiral spin liquid state
proposed by Greiter and Thomale [PRL 102, 207203 (2009)] using variational
Monte Carlo. In this state the bosonic $\nu = 1$ Moore-Read Pfaffian wave
function is used to describe a gas of bosonic spin flips on a square lattice
with one flux quantum per plaquette. For toroidal geometries there is a
three-dimensional space of these states corresponding to the topological
degeneracy of the bosonic Moore-Read state on the torus. We show that spin
correlations for different states in this space become indistinguishable for
large system size. We also calculate the Renyi entanglement entropy for
different system partitions to extract the topological entanglement entropy and
provide evidence that the topological order of the lattice spin-liquid state is
the same as that of the continuum Moore-Read state from which it is
constructed.
