Wildlife is a year-round component of living in Boulder’s foothills. Most of all, mountain residents worry about bears, in addition to mountain lions and bobcats. All three are a rare sight, they are very stealthy and they aren’t keen on being noticed by humans. Here are some of the many animals you might see if you live in Boulder’s foothills.
Bears

Although bears are very shy creatures, they are the most active of the Boulder wildlife troublemakers, mainly because of their penchant for dumpster diving. Keeping your trash in a bear-proof trash can and waiting until the day of pickup to take it out to the road can help deter bears from rooting through your garbage. We quickly learned it’s not just the trash you need to be aware of with bears. They are known to come sniffing around open windows and are very drawn to any and all food smells. Bears are very strong and can break into compromised windows. Don’t keep food or trash in your car and always keep your doors locked. Yes, bears can and will open your car door.
Mountain Lions, Bobcats and Mountain Predators


As a general rule, small pets should be kept indoors unless on a leash outside. Cats are easy prey for mountain lions and bobcats. Dogs are better kept indoors as well. If you see a mountain lion or bobcat, consider yourself lucky – they are a rare sight! Don’t be fooled if you don’t see them – they are very stealthy so just assume they are nearby.
