Am I the only one wondering exactly what stacking pattern, in a
rectangular trailer, gives them 9 extra cages in 2 m?

Divide the width (c2.4m) and the extra length each by three and you get
a size of cage around 0.8m x 0.66m.

Googling indicates that 800 x 715 is the "standard" "roll container" or
"roll pallet" size but there are all manner of variations/options.
