Coyotes can dig, and both coyotes and mountain lions can jump. Most coyotes and mountain lions are not anxious to encounter humans, but some have become accustomed to them, as people encroach further and further into the predator's habitat. If you see one of these animals, do not approach it.
Here is some good advice, from Wildlife Officer William Taber of the Inland Valley Humane Society & SPCA in Pomona:
"The best protection against coyotes and other large predators is to keep your pet inside, particularly at night, or in an enclosed yard with a fence that is at least 6 feet high, Taber said. Since some wildlife can scale such walls, he suggests topping it with a roller-top extension that makes the animal slide off.
Additional measures that Taber suggested against animals that might invade your yard include:
Installing motion-detector lights along the perimeter of your property, since most wild animals tend to shy away from lighted areas.
Feeding pets inside.
Spaying and neutering your pets to prevent them roaming and getting into turf wars.
Disposing of ripe fruit on trees or on the ground that might attract coyotes, or rodents, which in turn attract larger predators.
Trimming overgrown trees and bushes that may provide cover for coyotes.
Removing birdfeeders, since they also draw rabbits, squirrels, mice and gophers.
The CVMA suggests making sure your pets are leashed and trained properly, especially when walking in areas where they might encounter predators.
Taber advised hikers to carry a stick, a golf club or even a baseball bat in case they run across a coyote, mountain lion or even an aggressive dog.
Mountain lions, like other wild animals, generally avoid humans, but run-ins have increased as people have moved into the animals’ habitat.
“Mountain lions tend to focus on things that are smaller and things that are moving fast,” said Jon Klingborg, a Merced-based veterinarian who is president of the CVMA. “Walking or jogging with your dog may actually attract a mountain lion by stimulating the predator response.”
If you encounter a mountain lion, do whatever you can to make the animal know that you are not prey, Taber said. “Don’t start running. Stay calm and back away slowly to a safe location. Don’t roll into a ball. …If you have a rock or even a backpack, throw it. Wave the stick. Yell and scream at [it] and make yourself look human. Always fight back,” he said. “Keep an eye on the animal, but don’t stare them down. They’ll see that as a challenge.”
If you have a dog with you, hold it back. Don’t hike alone , he said, since animals usually won’t attack a group of people."
