Heck, the difference between herbivores and carnivores is mostly about their lifestyle and adaptations

Fun fact: Brown Bears are the least meat-eating carnivorous animal (hypocarnivore, with meat being about 30% of their diet)

Other fun fact: Polar Bears are the most meat-eating carnivorous animal (hypercarnivore, with meat being about 90-100% of their diet)

Yuuup. Critters gonna critter. "Herbivore", "carnivore", all of it: human sounds declaring observed patterns that allegedly indicate predilection/tendency, as usual. In short, mostly true often enough, but far less often as it implies.
