Hi,

Probably the best way that won't spoil the looks of the cages would be some kind of rotating blocks or metal strips.

But a quick and dirty fix until then would be two brackets an inch down from the top level of the glass door and a length of dowel or wood dropped in from above tight against the glass.

Or adding more of those locks on the sides of the glass door as well - might prevent it flexing enough to pop open from the top locks.
