* Diet: Red foxes have a varied diet that includes both animal and plant matter. They prey on small mammals like rabbits, rodents, birds, and insects. They also consume fruits, berries, and sometimes even vegetables.
* Teeth: Their teeth are a good indicator of their diet. They have sharp canines for tearing meat, and premolars and molars for grinding both meat and vegetation.
* Digestive System: Their digestive systems are able to break down both animal and plant matter efficiently.
* Observations: Scientists have observed red foxes in the wild, noting the variety of food items they consume.
* Stomach Contents: Studies examining the stomach contents of red foxes have confirmed the presence of both animal and plant matter.
Therefore, all these factors combined prove that red foxes are indeed omnivores, consuming both animal and plant material to meet their dietary needs.
