Cat combos are accounted for. Most ubers have cat combos, but some ubers have cat combos that are so strong that it becomes a core element of their usage and viability.

For these instances where an uber carries an incredibly strong cat combo, the cat combo will be weighed very heavily, and the uber will receive a higher rank regardless of the quality of them as a unit. The best usage takes priority, and if equal, the combo may contribute to giving one uber an edge over another if close placements arise.

For the most part, this will be a case by case scenario and depends on what combo is being presented and how relevant that combo is.
