A bat flying erratically during daylight hours, a raccoon slowly wandering down the middle of a road, a fox that does not run away when you approach, and a dead skunk in your horse’s corral.

What do these four wild animals have in common?

The animals in these scenarios are acting abnormally and could have rabies, a neurologic disease that is most likely fatal to unvaccinated humans and animals.

Rabies is a zoonotic disease—meaning it can be passed between animals and people—and confirmed cases have notably climbed in Colorado in recent years. With rabies clearly present in wild animals that are common in rural, suburban, and urban areas, it is important that animal owners:

Rabies on the Rise in Colorado

But since 2007, Colorado has seen an uptick in the number of wildlife testing positive for rabi
