  In this paper we consider the cop number of graphs with no, or few, short
cycles. We show that when $G$ is graph of girth $g$ and the minimum degree
$\delta \geq 2$, then $c(G) = O(n\log(n)(\delta-1)^{-\lfloor \frac{g+1}{4}
\rfloor})$ as a function of $n$. This extends work of Frankl and implies that
if $G$ is large and dense in the sense that $\delta \geq
n^{\frac{2}{g}+\epsilon}$, then $G$ satisfies Meyniel's conjecture, that is
$c(G) = O(\sqrt{n})$. Moreover, it implies that if $G$ is large and dense in
the sense that there $\delta \geq n^{\epsilon}$, some $\epsilon >0$, while also
having girth $g \geq 7$, then there exists an $\alpha>0$ such that $c(G) =
O(n^{1-\alpha})$, thereby satisfying the weak Meyniel's conjecture. Of course,
this implies similar results for dense graphs with small, that is
$O(n^{1-\alpha})$, numbers of short cycles, as each cycle can be broken by
adding a single cop.
