Two of the cubs lost their mom when she was killed trying to break into a cabin and the third cub's mom was apparently hit by a car.
The cubs are getting some help from wildlife experts at the San Diego Humane Society's Ramona Wildlife Center.
Experts are now trying to teach the cubs to be self-sufficient so they can make it on their own.
The center says they've passed their health exams and will remain there until they're strong enough to be released back to the wild.
