Obligate. You keep on using that word. I do not think it means what you think it means.
In all seriousness, pandas are still bears and can/do eat meat on occasion. Gorillas regularly eat insects and larva, digging up termite and ant nests. Our closest cousins the chimps are not only fully omnivorous, but are accomplished predators. Most herbivores (like ungulates, bovines, etc) will not pass up the opportunity to eat carrion, baby birds, small rodents, and the like.
