Depending on the speed the deer would die.
There'd be no more deer.
It would decompose
It's breath would smell like deer poop.
It would move on with its life
Then there would be less grass and food available for other deer and herbivores.
If the deer became extinct then ,all the greenery would overgrow , and all the animals that eat the deer would die as well because the deer was there main food source.
there would be many dissapointed hunters
If the deer population increased fivefold, it could lead to overgrazing of vegetation, which could disrupt the ecosystem by decreasing plant diversity and altering habitats. This could also result in more frequent conflicts with humans, such as vehicle collisions and damage to crops. Additionally, an increase in deer population could potentially lead to an increase in disease transmission within the deer population.
you would be ok even if you feel like turning into a deer whitch your not. But if you lick to much you might have to go to the hospital.
Hunter will think it is a zombie deer
no more hunting seasons
