Mammals:
* Carnivores: Lions, tigers, bears, wolves, foxes, dogs, cats, etc.
* Omnivores: Humans, pigs, rats, squirrels, raccoons, etc.
* Herbivores: Horses, rabbits, elephants, zebras, etc.
Other Animals:
* Birds: All birds are non-ruminants.
* Reptiles: Lizards, snakes, turtles, etc.
* Amphibians: Frogs, toads, salamanders, etc.
* Fish: All fish are non-ruminants.
* Insects: All insects are non-ruminants.
Note:
* While horses are herbivores, they are not ruminants. They have a single-chambered stomach and rely on their large intestine for digestion.
* Rabbits are also herbivores and have a unique digestive system. They practice cecotrophy, where they eat their own feces to re-digest the nutrients.
Ultimately, most animals that are not cows, sheep, goats, deer, giraffes, or other members of the Bovidae family are considered non-ruminants.
