The game of Cops and Robbers is a well known pursuit-evasion game played on graphs. It has been proved \citeboundeddegree that cubic graphs can have arbitrarily large cop number c(G), but the known constructions show only that the set \c(G) | G cubic\ is unbounded. In this paper we prove that there are arbitrarily large subcubic graphs G whose cop number is at least n1/2-o(1) where n=|V(G)|. We also show that proving Meyniel's conjecture for graphs of bounded degree implies a weak Meyniel's conjecture for all graphs.
