Here's why:
* Their teeth and digestive system are designed for meat: Wolves have sharp, pointed teeth for tearing flesh and a short digestive system that's efficient at breaking down animal proteins.
* Their prey: Their diet consists mostly of large mammals like elk, deer, moose, and caribou. They may also eat smaller animals like rabbits, rodents, and birds.
* Occasional plant matter: While they primarily eat meat, wolves might occasionally consume some plant matter like berries or stomach contents of their prey. This is not a primary food source and is usually accidental.
So, while they might nibble on a berry or two, wolves are fundamentally meat-eaters.
