Staffers and volunteers at Lake Tahoe Wildlife Care monitor their progress and clean and prep their food. Watermelon and grapes are their current favorite.
Contact is kept to a minimum so the cubs don't become dependent on their human caregivers.
Right now they are like any other growing family.
"They're exactly like toddlers," said Tom Millham with Lake Tahoe Wildlife Care. "They'll sleep a lot, night and day, and they'll get up and they'll play. They'll eat and whenever you eat and you have a full belly, it's time to take a nap."
The bears will stay here through the New Year, even going into hibernation. They will grow from around eight pounds to more than 100.
After their long sleep they'll be tested to see if are ready to be released back into the wild.
