For giant pandas, they don’t have to be prey, they just aren’t predators.
Their young get eaten, the adults aren’t particularly threatened by anything other than humans.
Red pandas are small enough that I’m sure they are prey. Probably for some large cat.











Wikipedia says otherwise, despite them still having many carnivore/omnivore features. It’s also -very- unlikely there haven’t been suitable prey species in their range in the last 2.4 million years.
Their faces, bodies, behavior, and various aspects of their metabolism are adaptations for bamboo-eating. They were omnivores, but they are no longer.

I like how everyone replying to me is giving pandas all these special asterisks to their classification that don’t actually exist or matter, when it’s literally just an exception to the predator rule, and has been for over 2 million years.
