The configuration shown above does not match the 'ntpq -p' output shown
below (which I've reformatted for readability).

puma and pussycat are most likely being rejected because of their
offsets.

However, these 5 systems _are_ using pussycat as their sys_peer (i.e.
they're synced to pussycat).

The configuration you included above does not show the peered hosts.
