  Lattice QCD can provide a direct determination of meson electromagnetic form
factors, making predictions for upcoming experiments at Jefferson Lab. The form
factors are a reflection of the bound-state nature of the meson and so these
calculations give information about how confinement by QCD affects meson
internal structure. The region of high squared (space-like) momentum-transfer,
$Q^2$, is of particular interest because perturbative QCD predictions take a
simple form in that limit that depends on the meson decay constant. We
previously showed in\cite{jonnaff} that, up to $Q^2$ of 6 $\mathrm{GeV}^2$, the
form factor for a `pseudo-pion' made of strange quarks was significantly larger
than the asymptotic perturbative QCD result and showed no sign of heading
towards that value at higher $Q^2$. Here we give predictions for real mesons,
the $K^+$ and $K^0$, in anticipation of JLAB results for the $K^+$ in the next
few years. We also give results for a heavier meson, the $\eta_c$, up to $Q^2$
of 25 $\mathrm{GeV}^2$ for a comparison to perturbative QCD in a higher $Q^2$
regime.
