is a mule deer a carnivore herbivore or omnivore
Best Answer: Yes, deer are herbivores. If you are unsure if an animal is a herbivore or not, check the eyes. Eyes on the sides of the head (like in deer, rabbits, mice, ect.) indicate that they are herbivores. Their eyes are on the sides so that they have better 360 degree vision to look out for predators.eport Abuse. Deer are herbivores, they eat vegetation rather than meat which is consumed by carnivores, and animals consuming both such as man are omnivores. Stegosauridae were herbivores, T-Rex and Velicoraptos, carnivores.
