What distinguishes the margay's occasional plant consumption from classifying it as an omnivore?

Answer

The documented consumption of fruit or leaves is incidental and not a necessary dietary pillar.

To be considered an omnivore, consumption of plant material must be regular and significant enough to form a core part of the survival strategy. For the margay, any plant intake is viewed as supplementary, perhaps for roughage, and does not meet its primary energy needs.
